Hello, I'm new to chickens and to this forum so if I ask stupid questions that's probably why I got 7 supposed pullets at TSC 11 days ago. I was told they were about 10 days old then. They were from a mix tub. Said possible breeds could be BR, RIR, BSL, or ISA Brown. I figured they were ISA Browns by searching images when I got home. 2 of them look different now than the other 5 in color. I don't know what breed they might be, but I think they may be roosters. They are supposedly 3 weeks old today. Here is 1st "maybe roo". He's built taller than the other one and has a little green to his legs. He's getting cocky with the other suspected roo. Flying at him with legs forward. Pecking him. Staring him down. Roo? What breed? Pullet behind him looks like the others. Roo #2? Is shorter, heavier body, white legs. Calmer disposition. Here's my favorite girl. She's so sweet and calm. A little lighter in color than her sisters too. ISA Brown? Mainly just want to know, are the top two roos? If so what breed? Thanks in advance.
