I am having an issue integrating my 4 hens with my chicks. They are in desperate coops but their runs connect to where they see each other. The chicks have had a temp run the at shared two fence walls with th big girls. It ha been this way I've 2 weeks. Yesterday we took down one of the temp walls to try inter-mingling and well, the hens were less than welcoming!!! They jumped on a few chicks an there was speaking an feathers, it wasn't pretty. So back to seperation it went. Later I tried taking just one chick in with me, well that went about the same. My big girls at being bullies, an that's gotta stop. I have 12 older chicks outside, and more inside that will be sharing common open free ranging yard w made them, so they have to be along!!! PLEASE ADVISE!!!!!
