I have 6 white leghorn pullets that I'm about to move out to their coop. They are 6 weeks old today. I have a 5 week old Silkie who we got as a pet, but I'm thinking it might be a roo. I have kept it separate from the others due to their growth rate/size difference. I'm wondering if/when it would be possible to put him with the pullets. They're so much bigger & more mature than he is right now. He's barely getting tail feathers & they are twice his size & fully feathered. Will it be possible to integrate them, or should I work on a separate coop for him? Sorry for the questions, but this is our first time with chickens.
