Sorry about losing the chicks. That's what I hate about turning the light on and off. I love letting broodies do the hatching. Yes, you just count the days, make sure she has access to food and water. You'll be surprised how much they leave the nest, how many times the eggs get cold and how many still hatch! The only thing I would do is after about three days into hatching or when you see the hen is spending more time trying to take care of the chicks then setting the remaining eggs is to finish them in the incubator. In my experience I always have fully developed chicks that didn't make it because mom had to take care of the chicks. Otherwise, let her have at it, it's a very interesting process to watch. As she gets close to hatching I'll give you some more details on how to tell when she's "locking down" and then when a chick is hatching....oh, and to wear gloves when you try to see what's going on under her!oh, and I killed some of my newly hatched chicks because in the chaos of the puppies, i forgot to turn on their heating lamp that I had turned off during our 100 degree day. super fail!
i have a SFH that went broody so i'm giving her the eggs for a few days to see if she can raise the chicks better than me!
i've never worked with a broody as my incubator before. any major to dos/not to dos? or do i just give her eggs and let her do her thing?

Quote: Well darn, that's not good. Sorry to hear.
Oh my gosh! How scary! I've heard how crazy broodies can be but man, that sounds downright terrifying. Glad she settled down, hopefully the rest of the week is quiet.I had a drama today. One of the broodies went to poo and got lost. She tried to go to her old nest and found a new mother with chicks there. She went crazy and attacked the chicks, killed one, took a quarter sized piece of skin off another, and tried to break the neck of the Icelandics babies. Luckily I had just gone down to take some pics so I grabbed her before the mother chick pecked the broodys eyes out.
The little one that was hurt is shocky, I put neosporan and blu kote on the wound, but that's a BIG missing piece on a 3 day old chick. I don't know if it will make it. And of course, the icelandic eggs got cold while Catalina was out on her rampage.
I was shaky for a while afterwards, I thought Catalina might go for me at one point, she was like the hulk chicken. As soon as she got her eggs she calmed down and started to purr and ate out of my hand. Speedy the rooster was trying to figure out who to defend, luckily he didn't run in while I was hauling catalina out.
I have never seen a hen do that. Do you think it has something to do with her being the head chicken? She was sitting WITH the other hen just 5 days ago, I moved her to cover these other eggs since she had only been sitting for a week.
Deb, I got some more of what I think are Iowa blue eggs today from the egg swap, but no broodies to stick em under so they go in the bator. Hopefully from 2 batches Ill get some girls. Ill ask what they are a bit later, but they look the same!
Ok, I want a CALM chicken week now, with no surprises! In fact I want EVERYONE to have a calm chicken week!
Edit: Also, if anyone is looking for thermomoters, Amazon has infrared thermometer as their 1 PM hourly special.
Congratulations!
