Okay, thank you. The splash & blue are one age and the 2 blacks are younger. So maybe the blacks are boys too and they just haven't 'caught up yet'? Is this breed slow to develop their combs & wattles? Can someone post a pic of an adult hen & roo for me so I can see the difference? What age do you think I should be able to tell at? The blacks are 3 mos old and the splash is 2-4 weeks older than they are. I can't remember what the guy said 3 mos ago, I just remember they were from different 'batches'. And the splash is a lot bigger. Maybe I'll go take another pic of the 3 of them standing together (the blue ran off in the farmer's field and we couldn't find it anywhere, so we're assuming it got eaten by a creature of the night). I'll take one of a close up of their heads too. Thanks!
