So I got 6 buff orpingtons that are 4 weeks old now. I currently have 4 faverolle hens just over a year old. I plan on keeping 3 of the 6. My neighbor wants one. They have one barred rock that's been by itself for almost 2 years now. Last time the introduced a chick at 13 weeks and they thought it was a hen but was a rooster. Their barred rock pecked it's butt bare and raw they had to separate them. I was wondering they want the Chick after its feathered but I think that's too soon? It's a mean hen so I feel 16 weeks would be the best because she would be big enough to defend herself at 6 weeks she would get beat up. What do you think? I was even going to suggest adding 2 instead of one so the transition would be better.
