I just discovered 2 of my young guineas (7.5 weeks) fighting and bloody. They were pecking at each other and both of their faces are messed up. What should I do?? Their shed is 49sq ft for 10 of them, all raised together. I’ve had no problems so far. They’ve been outside all day so I can’t see how it can be overcrowding. Should I get rid of the more aggressive one? Help!
