Sorry; I did not mean to heat up the thread by asking about fighting breeds. I was simply trying to understand if it was a factor injuring the hens or it was more hormone. I have learned a couple interesting things here. I was aware they tend to have fewer health (especially reproductive) issues, but did not know the mature roosters can actually be better behaved. Fascinating!
Anyway,
@AnnetteS2020 was your question answered? I believe your best bet might be to separate him until he matures and go from there. Right now, it sounds like his behavior is more likely from the hormones and less likely from the breed, but once he matures, you’ll probably know for sure.
