We have a bunch of chicks, "assorted bantams" of all shapes, sizes, and colors. We had 15 yesterday and have 14 today. They were born around the end of February and are getting pretty good sized now. My best guess was 6 roosters and 9 hens. One of the roosters, a very small white and black one, came up dead in the pen. I had just started noticing some aggressive behavior by one of the larger roosters the day before. Do y'all think the other roosters could have killed him? I have a very secure new pen I just built and there was no evidence of any predators entering the pen. His neck and under his wing had torn looking wounds with a few feathers missing. Do I have to get rid of more roosters soon to prevent them fighting?
