This black one matches the black one I thought was a rooster, but I've seen this one lay an egg and I tell them apart because she doesn't have ears like the other one...
Here they are together:
And then again a few more pictures of Pookie...
That's my flock... If those eggs are fertilized there is a rooster hiding in here somewhere?!?
If the entire flock is shown in here, then no roosters. The black ones are definitely hens- it is bit of vague answer but they have "totally hen body type, comb, face etc".
None of them are showing any obvious roo features. But I did do a double take at the columbian wyandotte (the mostly white with black on neck and tail) because that comb is huge even for a laying hen that has a rose comb. But it's still within the range of hen rose comb size. It has no roo feathering or other traits, though. Another reason for double take at her is because that's an uncommon breed.
If all birds are this age, there would have been at least a few attempts at crowing from any roos.
If I had even the slightest clue, idea or equipment to "set some eggs" I would... They sure look fertilized to me and everyone who sees them?!? Strange!! Chickens are fun!
