Hello everyone, I'm a new user and this is my first post! I wish it was a happier one. NOTE: My chicken walk-in coop is built within a pig pen (we have a Kune Kune pet pig), but before last year we never had a rat problem, even with the pig. But with the pig living next to the chickens, the rats are pretty persistent. Last summer, two of my female Pekin Bantams had chicks. Altogether there were about 12 chicks. In the first two weeks, i found one or two dead chicks. Now i presumed this was of natural causes, because the chicks didn't looked damaged, they were simply lying dead in the hutch. The next week, I went up to feed them and noticed a chick was missing. I searched and searched but couldn't find the chick. It was THEN I noticed a small hole underneath the fencing. This concerned me immediately, however as we had never had a rat problem I thought maybe the chick had wondered off down a mouse hole, as the hole really wasn't very big. But then all broke loose, I ended up losing ALL of our chicks within the month. I was devastated! Then, one morning I went up to my chicken coop, and was shocked when I saw the body of one of my hens under the hutch, with its head missing. It definitely 110% was not a fox, the damage was nowhere near severe enough. There was a large hole next to the coop and inside the coop. I had tried my best to fill them in, we even put posion down them but nothing stopped the **** things. I live in the UK (is this an international forum?), so it couldn't really have been anything else. About 6 monthes ago I moved the chickens hutch down beside the house because I couldn't bare to leave them up there. They were fine, until about two months ago, I open the cage and there was yet another dead headless hen, and I noticed a gnawed hole in the bottom of the hutch where a Rat had gotten in. So, that is my rat horror story. The same day I found my dead hen, I moved my remaining hen and cockerel into a cage inside my house (they still wonder free range around the garden during the day though!) Now, as much as they adore being inside the house, they are making a mess! It is also coming to Spring and they are starting to mate. I'd love for my hen to have another batch of chicks, and maybe we can restock our flock, however they can't do that whilst they're inside as there is no room, nor can they do it whilst there is a rat problem!! Is there any suggestions for helping me rat proof my coop so they can move back outside and raise chicks? I'm very worried about them going back there but my parents are getting fed up of the mess they are making inside.... We have tried: Rat poison Clearing up food so there is none lying around at night time Filling in the holes (although that is only a temporary fix) Moving the chickens Wiring over the holes But none of the above has worked. We were thinking of cementing the floor, however would rats eventually dig through that too? I was thinking of putting chicken wire (the strong thick wire, not the flimsy gapped wire) along the base and covering the ground of the coop, then placing wooden planks to cover the wire, and then placing soil etc on top of that to make it better for the chickens. But I'm thinking the rats would probably get through that too... I'm going to raise the hutch, as at the moment it is not very low off the ground. (It's a two story rabbit hutch, but it does very well for the chickens!) (Until two months ago) Here are pictures of the coop the chickens were in last summer, my boyfriend and I built it: (NOTEe small wooden shed is the pigs house, the chickens have a hutch inside the wired coop). Above: The rats hole has now run all along the front of the pigs house (where my sister is) right around the front of it to the back of the chicken pen. The hole around the front of the pigs house runs around to the back here ^^ Sorry for the long post, and many thanks for reading!!! Any suggestions?
