So, my bigger and more aggressive Baard Rock might be a Roo but they were all pullets supposedly. They are 3 weeks old. This one is bumping chests, flapping wings, and just randomly picking on the black sex link and Lace wing. They then gang up and pick on just one, usually the black sex link. HELP, is this normal? I separated the1 week Leghorn and Silky from the 3 because of age and their size. Now I'm kind of worried about how to put them back together. The larger ones were scratching around so much the water was gone almost immediately and they little ones couldn't reach the hanging waterer so I put them in their own box. Should I have done that and what is the best way to house these growing girls? I have the 3 in a long box that a trampoline came in. The other 2 younger girls are in a large plastic crate. I'm almost ready to take the Barred Rock for a long walk, but she or he is getting feathers and they are so pretty.
