Hi! I have 6 three-four week old silkies, 4 b/b/s and 2 partridge. very cute. I was wondering if there were little signs or indicators I could be looking for in terms of gender...1 partridge and 1 black are a bit bigger then the others, and are quite noisey compared to the others. Just their personality or signs of a roo? I have no idea if im starting to see any kind of acorn comb and what not, this is my first time, and they are pretty small still. Any input? Thanks!
