Hi all. This is a bit of a long read but hopefully my story will help some others learn from our mistakes and help keep your own flocks safe. We also welcome any advice on hopefully helping our one injured hen recover.

Some of our flock including our beloved rooster Leonard who sadly was one of the weasel's victims.

Our egg laying flock was 15 strong up until the past couple of weeks. We discovered we have an Ermine living in the woods nearby our coop and over the course of about a week he/she gradually took our flock down to just two remaining hens. Since the initial attacks, I've gone to great lengths to try and predator proof our run including installing 1/4" hardware cloth top to bottom, installed a full roof, and a predator apron all the way around with more hardware cloth. I thought I had it all locked down before this last attack but unfortunately, I discovered that there was a tiny gap where I had run out of hardware cloth on one roll and then overlapped the next roll and carried on. You can actually see where the Ermine tried digging, hit the wire, and then moved over a few inches and tried again. They did this all the way along the perimeter of the fence until they finally found a tiny gap they could squeeze through.

IMG_5302.jpg

You can see several spots along the bottom of the run here where the ermine dug down, hit the predator apron under the dirt and then moved over to try again.

A few days before this most recent attack I also took one of our security cameras we already have and installed it in the run to keep tabs on the chickens. I'm glad I did because while I was out at a 4-H event I got a notice of movement detected and sure enough, there was the Ermine attacking one of our two remaining hens. I called my wife, and she ran out from the house. She interrupted the attack, and the Ermine ran off through the hole it dug its way in through. This was the fourth attack in total over about two weeks and all attacks happened in the middle of the day, approximately 1-3pm. Our chickens always come in at night with the door closed to the run, so they've thankfully been safe when inside the coop itself.

Video showing the attack. The Ermine squeezed under a seam between two sections of predator apron that wasn't secured as well as it should have been. They then dug under and into the chicken run. The door was open to the inside the coop where two hens were at the time. This video starts as it is chasing one of the hens out into the coop. It might be visually disturbing to some so please watch with caution. Also, I've seen some folks think they only need to do hardware cloth around the bottom of their run to stop a weasel. I'm here to tell you that it is absolutely needed all the way up, even the roof if you don't have something solid like we do. If you slow this video down at one point you will see the ermine jump about half way up the wall as it chases the hen. These walls are all over 6' tall. Whatever distance it doesn't jump it could easily climb the rest of the way.

This clip shows the ermine releasing the hen once it hears my wife coming over from the house. Watch how fast it disappears back down the hole it dug under the predator apron. It even pops it head back up to take a quick second look before it ultimately ran back off into the trees.

Our one remaining hen is clearly scared. She is still eating and drinking water, but she doesn't like to be on the floor of the coop for longer than a few minutes and then she gets back up to heights. I am not letting her back outside currently while I try to get rid of the Ermine problem.

I've re-doubled my efforts on the predator apron. I overlapped more hardware cloth and made the apron itself wider. I found the last entry point and fixed that and even ran another apron on the inside of the run along that side. I think I have all the weak spots identified but I thought I did last time also. The problem I'm facing is the coop and run were pre-existing, and the building is very old. It is on a concrete foundation thankfully, so nothing seems to be getting into the coop itself. But I've had to retrofit everything onto our run. Ideally, I would have just built it right from day one but money isn't unlimited, so we are trying to make the best of what we have.

I've also gone to the length of building some weasel box traps and I've placed those out around the outside of the run and in the forest nearby where I think the Ermine must live. I've been checking daily for about a week, and I've only caught mice so far. I'll keep trying but I know weasels are notoriously hard to trap. This is maybe a bit over the top, but I've even gone so far as setting up one of our small Google speakers in the run and playing chicken sounds on a loop to hopefully make the weasel think hens are back out in the run. My hope is they'll come looking and smell the bait in my traps. I've only been doing that experiment since yesterday, so I'll have to report back later if that actually works.

Lastly, our poor hen who was attacked most recently is badly injured. The weasel latched onto the back of her neck as they do. There were two small puncture wounds that we cleaned and they clotted up fine on their own. But she seems to have developed wry neck as a result of the attack. She holds here head at a weird angle and seems to have a hard time turning it to the side. She is still eating thankfully although it's a bit of a challenge for her to get her "aim" correct so we are trying to help her with that. She's drinking water a bit but same problem there. She also can't stand very well on her own right now. Her balance is off and she tends to just roll over to her side if she tries to walk. She can move her feet and wings, so she isn't paralyzed, but it seems like maybe there is nerve damage or something. We know we may not be able to help her fully recover but we are going to try our best for at least a few days to see if she has any improvement. We also don't want her to suffer so we know we may have to make a difficult decision here soon. If anyone has been able to successfully help a hen recover from such an attack, we'd really appreciate whatever tips you have.

We used a small pet kennel we have to set her up with some food and water. She has spent two nights sleeping in here and we take her out during the day to do some "chicken physio" and help her eat and drink.


Total side note, of all the predators I've read about and tried to be prepared for I feel like a weasel has to be one of the worst/hardest ones to thwart. Fingers crossed we've done enough to protect our run for our next group of layers.

We have about two dozen chicks set to hatch this week. With only one hen in the coop currently I'm wondering if I can introduce them earlier than I normally would after they're done in our brooder setup. I just don't want her to be sad on her own. Hopefully our other hen heals up and can rejoin her also. I welcome any thoughts on this.

The past year my neighborhood has had a disaster with predators. Weasels were the worst as they are very difficult to keep out of any enclosure. They also attack in family groups. I hope your trap works. You may have more than one, so keep it baited for several days after you catch one.

I ended up using poison (Fly Bait). They fall asleep and die.

Also, if you have any lavender essential oil, put a drop on one of the wounds. It is anti microbial and will help the hen to relax.

Putting the apron around everything with 1/2" hw cloth is challenging. If I build another one I think I will build the apron first. Lol Hope you catch that weasel and your chicken recovers 100%! Happy to hear you have new chicks hatching soon! Hopefully a divider is all you need to separate her and them.
 
Sorry to hear about your losses. That is a terrible thing to have to deal with.

:old Way back in the day when I was a young kid, I had almost 100 rabbits. One winter, a mink or weasel got into our shed and started killing my rabbits. We did not have the money to predator proof the rabbit house against a weasel, so that was pretty much the end of me raising rabbits. Sad thing is that the weasel, or mink, just don't kill only one animal for food. They kill as many as they can, it seems, just for the fun of it.

I am thinking that you really got to get good at trapping those weasels. Sounds like you have a good plan to predator proof your weak spots, but those weasels will be looking for any weakness and take advantage of it. I don't think I would rest easy until I had trapped them all and removed the threat.

I hope you keep this thread updated, because you really have a nice setup for your chickens. I would be really interested in how you solve this problem. Even though I don't currently have a weasel problem, I would like to know how other people deal with their situations.

Anyways, I wish you the best of luck and hope you eliminate your weasel problem as fast as possible.
 
Its frightening to know a mink or weasel will go to so much trouble hunting for an opening
Yes, it is. I guess the one positive is this little critter is helping me identify all the weak points in the system. I'm hopeful I have covered everything now. But I'm even going to go to the added extent of dumping some gravel on top of the apron now just to make it harder to even dig down to that. It will also show me any spots where it is trying to dig in because I don't have the apron buried everywhere currently, just on the one side in that photo I posted.

Our injured hen stood on her own for the first time yesterday. It was for a short time, but it does seem like she's slowly getting a little better. I am taking her to the vet this afternoon because I think she might need some antibiotics etc. I'll update this post for anyone interested in how she ends up doing.

I picked up some beef liver for the weasel traps so I'm going to try that today. It's bloodier and from what I've read that is very tempting for a weasel. I'm also going to do a slight modification on my trap boxes and put some vents in the back of them where the bait is so they can hopefully smell it better.

Yeah, you're bang on about the weasels. The first attack we had it took out 7 chickens in one go. It left 5 of them piled up on top of each other, one inside the coop and managed to drag the 7th one off. This was before we beefed up the run with hardware cloth so it was easy for the weasel to get in. This attack was also in the middle of the afternoon. My wife and I were even outside on the other side of our property with our farrier getting the horses trimmed. When I walked over to the coop afterwards I found the aftermath.

The thing I find interesting is we had the chickens out in the run every day all summer and had zero issues. It was only in the last few weeks the weasel showed up. Since we are heading into winter, I'm thinking it's endless supply of mice is probably getting harder to find so it saw the chickens as an easy target.

For now, the chickens will stay inside the coop which is thankfully pretty spacious. But eventually I'll have to let them out even if I don't catch the weasel. I'll just have to do everything I can to try and block any possible entry.

FWIW, I live in northern Minnesota and my chickens live in their coop for a good 5-6 months out of the year. They just will not go outside if there is snow on the ground. I built my coop with about twice the recommended space per bird normally allotted. They make it through the winter months living inside the coop.

:fl Hope you catch and eliminate that weasel(s).

That's good to know. I did fully cover the run to keep the snow out for the most part. Before I did that, I noticed the same thing after the first snowfall. Everyone just refused to go out. I might just need to add some more enrichment stuff to the inside of the coop. I spent a lot of time adding natural branches, treat holders, dust bath, and even a swing in the run lol.

Short update. Our injured hen managed to stand up on her own this morning. She's kind of leaning on the edge of the kennel here in this photo to help balance herself but she seems to be headed in the right direction. Her neck is still definitely twisted to the side but she's eating a little bit. We will see what the vet says later today.

As for the weasel traps, caught another mouse when I checked them this morning. I have some beef liver now so I'll re-bait the traps with that later. It's supposed to be warm here today so hopefully that makes it extra ripe and stinky to attract the weasel in.
