My friend is brand new to chickens, and she's been brooding 4 chicks together for 10 weeks now. 2 black Austarlorps, a Buff orp, and an EE. The run finally got finished and she put them all out in the coop and run together. The EE started attacking the black Austarlorps and causing bleeding around their beaks. The BO is smart enough to stay out of the mess and is doing fine. My friend is beside herself on what to do. She's took the EE out for now and put her by herself. They've been together since they where little and just now, as they get put into a nice big place the EE starts to attack. What's up with this? What can be done? Help?
