These guys are 5 weeks old, give or take. The two white are CornishX from TSC, the black just said "Black sex link" on the bucket (I tried to pick the ones with yellow dots on their heads, as I read someplace), and the other two are Speckled Sussex. I think that one of the SS and one of the black ones are roo, but I am not at all sure. I also have 16 Silkie chicks that are 2 weeks old. I only lost one of them after shipping, and they sent 2 extra, so I'm happy so far. I have white, blue, and splash. These are my first Silkies, but they are insanely cute. I doubt they're very impressive specimens, but I love them and don't plan to show. I also have 6 EE beauties I got from TSC. I'm no longer allowed in the store without my husband! I know these guys are too young to tell, just wanted to share the cute.
