I currently have a small backyard flock, and two days ago I added 3 new hens. Prior to adding them to the flock, I kept the new hens in a crate close to the others so that they could become familiar with each other before putting them together.. two days ago I added them... so far I think that the fighting has been pretty minimal and all chickens seem to be eating well and I even got a couple eggs yesterday from the new girls.. However, they are fighting a little over the nest boxes... I went in the coop yesterday and all of my hay was all over the place, so I know that they were not happy. and one of the nest boxes the new girls have roosted in and pooped all in the box. My question is how long will they fight over the nest boxes? Is there anything I should do to prevent it or make it easier? and How do I keep the new girls from roosting there?
