Ok ok, I know there is much debate about weather feather development can identify which sex a chick is... But I am in a scenario where I think there might be a possibility and I'm wondering if anyone else has a similar experience? I received on Christmas Day, 2 day old chicks in the following quantities 5 x Caramel Queen (verified sex link, cross of light Sussex Hens and Wellsummer rooster) 6 x Light Sussex straight run 6 x ameraucana straight run 5 x Barred Rock straight run All came from a local hatchery of heritage breeds. We picked them up Ok, so bearing in mind I KNOW the caramel queens are pullets, I've been observing the other groups of chicks and comparing them all. They are all very feisty, so my observations are not based on attitude alone, or overall size, but wing development. All chicks are 12 days old today. The caramel queens are very well feathered. In comparison, I see that half of the Sussex chicks are feathered like them (I suspect pullets) and the other half have a more upright cocky stance with much less wing feather development (suspect cockerels). Same for the barred rock except only 2 with the more pronounced development (suspect 2 pullet, 3 cockerel). The anomaly is the ameraucana - they (all 6) seem to have the same degree of feathering, similar amounts to the queens. Either they develop differently or I've got 6 pullets... I'm hoping for the latter! I'll upload some pictures for your thoughts Maybe I'm nuts!
