So I have 3 chicks I am trying to figure out if they are Roos or not.. They are 13-14 weeks old!!! This is my red boy - I know for sure hes all boy... Now this is my little Black EE mix.. No Red, No Spurs, and saddle feathers appear to be curved - but dang that tail looks boyish... And this is my white EE mix chick.. Im praying it was a hen, but Im thinking boy.. Just b/c of the red comb.. Other than that no spurs and saddle feathers appear to be curved. Also he/shes tail looks like a hens, no "rooish" feathers like the red above!!!
