I hatched 22 eggs, (but one didn't make it.) They are now 5 1/2 weeks old, and out of 21 chicks, I'm pretty sure I have 9 roos. The roos have started pecking each other and fighting, and today I have 2 bloody faced roos. I want to "get rid of" all but 1 roo, but I'm not 100% sure which ones are indeed male. They are WAY too young to be fighting like this...I wanted to wait a while until they are older and I'm 100% positive that I'm eliminating the correct ones. One of the bloody ones from today is one of the ones I'm unsure of. Help!
