I've talked about this before, but she's really out of hand at this point. My Speckled Sussex, Pippa, is doing her best to take a chunk out of my chicks. The chicks are 7 weeks old now, and were introduced to the coop at 3 weeks. They live in a pen that sits adjacent to the bigger pen we have for the pullets, but is separated by chicken wire, thin fence posts, etc. I took the advice I'd gotten previously here and installed a small door in this area so that the chicks could go back and forth between the two pens, with the hopes that they would integrate themselves with the pullets and eventually live in peace. I made the door a bit smaller than the dimensions recommended, but my pullets still manage to fit their way into the chick's area. Namely, Pippa. Now, whether Pippa is in her pen or on the chick's side, all she is interested in is biting and chasing the chicks. I've sat in there and watched her scope them out. If Pippa is removed from the situation, everything goes okay. There's some standard bullying going on, but the chicks manage themselves. But if the chicks even see Pippa, they let out a little "eeep!" and get as far away from her as they can. She will NOT focus on anything else if she and the chicks are in the same area. Pippa has started to lay and is giving us some pretty steady eggs, which I think is impressive for the age she started at; 18 weeks. Is this just her being crazy? Should I just wait it out for when the chicks are bigger and can hold their ground better? I'm just worried they are outgrowing their little chick living space. I don't want them to be crammed in there, but I also don't want them to be terrorized by Pippa all day. As of now, the door I made is closed. Please let me know what you think would be best to do. Thank you.
