Newbie here out of desperation. Spent gobs of time and money on a giant new coop. Moved everyone in yesterday, tickled to death, and the birds have lost their fool minds. I feel completely ignorant when I thought I was on top of my game. No new birds, and everyone's been together since day one, literally. My gentle giant, a BuffOrp roo, is beating everyone up. Submissive birds won't eat, even though there's dang near a week's worth of food in there in efforts to reduce problems. It is vicious and vile in there, and I'm embarrassed to say I'm a little nervous being in with them. Did I do something wrong? Normal? Timeframe to peace? Intervene? How? Amount of Advil I should immediately ingest? Thanks in advance.
