This is my family's second generation, we were lucking with our first and got all hens. This batch was not so lucky. The last photo we're 100% sure that he's a roo, but the first two we're not sure on. One of the bantam silver sebrights is a possible roo, because he has his comb filling in while the other doesn't. We just kind of want to have confirmation on their genders. Thanks for the help. (:
The other EE is hard to tell from the photos. With my barred rock pullets their combs are yellow and quite small. I'm sorry, I know that probably doesn't help much for now. Especially if you'll have to find different homes for any roos. The breeds can vary so much and sometimes just depends on the bird himself/herself. Good luck with your flock! They're all very nice looking!
