i have two brown hens. They were best friends when I got them just in April. Then one got attacked by the neighbor’s dog and had to live inside the house to recover and heal. When I tried to reintroduce them they are going against each other with a force and visciousness that I would’ve never expected. I left the healed chicken in a dog crate in the run for two weeks now to get them familiar again, but had to cover the crate with really small Mesh wire because they were pecking each other bloody without it through the cage. Then I let one run free and lock the other one on the chicken house and rotate since one week now. They still peck through the wire Mesh, but can’t hurt each other. Today I tried to let them meet each other and within seconds they were up in the air fighting like 2 fighter roosters. I separated them immediately, but one of them broke a toe in the mess and is limping now. They seem equally strong and none of them shows any sign of submission. I have no idea what to do?????
