I have two spoiled pet chickens who live in a large parrot cage in my home. They free range outside during the day and come into there cage ever evening. One chicken is a bantem and the other one is a leghorn / rhode island red mix.The bantem sit on and raised the other one for me. The problem is now they have gotten older and started fighting. They get along well when they are outside, but when they come into there cage that is when the fight starts. It gets pretty bad sometimes between them. The little bantem seems to be whipping and getting the best of the big one , who is twice her size. The bantem is the aggressor, starter,and the finisher. I am afraid one is seriously going to hurt the other,and I'm pretty sure that it will be the big one who is going to get hurt. The little bantem just want give up and seems to be a prize fighter with feathers. I don't understand why this is happening. The little One is the big ones momma;& they have always got along great till now. Please help !! Should I separate them or just let them fight it out ?
