They are still a little young to tell, but I'm leaning towards the following:
1. Cockerel - slower feather growth, larger and pinker comb, overall look of body
2. Pullet - more feather growth, smaller comb
3. Cockerel - ditto from #1
They are from Fancy Chick in Ohio but they are free fire lines. I bout 7 straight run chicks an was 2 and 2 in the first 4, so was hoping for at least one more pullet.
