For the time being he can stay. When he starts to make too much noise he has to leave.They are cute!! At least you got 2 hens! Are you going to keep the rooster?
If he starts to roost , I want to put him in a separate tiny coop, that is rather dark. It has an auto pop door I can set on a timer. So he can get out and crow after 8.30 am.
If it doesn’t work out as I wish, I hope to get a new home for him.
