My latest babies (the ones we all watched together) are now 4 wks old. I'm trying really hard to figure out roos vs girls, but am not 100% sure except for a couple of them so far. So, here's my questions.... I have 7 BOs. 3 of them have VERY huge combs compared to the others. 2 of them have virtually NO comb at all yet. the other 2 are somewhere in the middle. Which is more important to consider? Comb SIZE or COLOR? On the BRs I'm looking at leg color, feather color and comb size. I'm still waiting for them to shout 'roo' at me, but I'm not really seeing it yet. There are a few I'm sure are girls based on their very dark legs and darker coloration, but the rest are a toss up. At what point can I make a positive ID? I am looking foward to figuring out which ones I'm able to keep, which are going to my friend and which (roos) I am going to have to find other homes for... If I can get my self organized, I'll post some pics, but am I missing something here or is it still just too early to tell?
