I think you are going to do fine! It's taken me years to get to the no interference stage. I've tended to make situations worse by interfering.Hello and thank you for your reply!
I'm not entirely sure how old he is. We rehomed him from a lady on a facebook rehoming page who also didn't know much about them except that William was half Shetland and the girls were battery hens. We got him in October and he already had his full comb and giant wattles and was crowing all over the place and getting frisky with our most attractive hens, so I think he had already reached sexual maturity. Our hens only recently came back into lay for the spring, so I think his hormones have him all worked up. We have a couple extra coops lying around, so can house them separately if need be.
Only two of their fights came to any real blows so far today, the rest have been mostly chasing and flapping. I will open up the largest of our spare coops today and see if they choose to roost separately. Both have groupies amongst our hens, so hopefully things will shake out naturally with the division of the flock and each will get to hang out with his favourites.
We tend to try and intervene in their politics as little as possible, preferring to let them work things out for themselves. So far, that has not been problematic, but waking up to poor William's distress calls this morning was a bit harrowing.
(One would think I'd know better after raising three children.)
