I need advice as to why on earth my chicks are fighting. They are almost 6 weeks old, and are very sweet and affectionate to people. The hatch includes 8 cochin bantams and 6 production reds. The mom is not their mom but was broody and I put eggs under her. She is a cochin bantam naked neck frizzle mix. A few days ago she started attacking all of her standard size chicks. I had to separate them from her. I put everyone out in the sunshine today, but when I went outside to check on them, I noticed that the little frizzles were fighting horribly! It was just horrible. I included a video because I want to show y'all exactly what was going on. Please don't say mean things to me about filming them fighting. It was just a second, and I was able to figure out the two that were causing the fights. The two fighters are by themselves. And the two with injuries are inside the house. I just have never seen fighting like this in chicks. It is scary and I don't know why they are doing it. Is this something that can be fixed? Why are they doing this! ?
