Let's start with some background info. I have one coop that was on my property when I bought it. It's about an 8ft x 8ft enclosure and we added 6 nesting boxes to it. I bought 3 pullets (about 15-20 weeks per hatchery) and put them in there. There is Dottie the SLW, Agnes the Australorpe, and Blanche the Barred Rock. They have been growing so much and just last week Dottie laid her first egg. One of my friends also gave me her RIR hen, Henrietta, and the coop that she had. I'm not sure how old she is but my guess is around 2 years and is an excellent layer with an egg almost every single day. So, here are my questions: 1. Henrietta is a jerk. It's why my friend gave her away. She charges at me sometimes and is pretty aggressive. She does like my husband though and even lets him pick her up. Why is she so mean? How do I fix it? 2. Henrietta likes to sleep and poop in her nest boxes. She poops on top of the hen house too. She also refuses to use the roost, even though she used to sleep on the one in the other coop before I got the little girls and moved her. 3. The last two days that I have gone out to check on the chickens in the morning the egg that Dottie laid has been on the ground, crushed and empty. Is it possible that its getting kicked out of the box since she likes the top one? Or is it possible that the other chickens are eating it on purpose? Is that something I can stop or do they have to become dinner? 4. Do I need to move Dottie into the coop with Henrietta since she is laying now? Will she end up getting hurt since Henrietta is so mean, even if I do a gradual transition with a dog crate? Dottie is the dominant one in her current coop, but not aggressive.
