About how old do you start noticing the "pointy" Hackle and Saddle feathers on chicks (if they are roos) These are mixed with a Red Sexlink roo and either Leghorn, blacksexlink or red sexlink hens. My babies are almost 4 weeks and all look very similar (comb growth) except one or two that are noticeably different so how soon can I start to look at the hackle and saddle feathers to see if they are roos or not?
