I have 9 chicks with their broodies in the flock. 6 are roughly 6 weeks old and the other 3 are 5 weeks. All but one are cochin x leghorn and I am trying to evaluate sexes of the chicks. I have 4 chicks that have much more pronounced combs and wattles (and much more red) than the others and I have witnessed 3 of these particular chicks chest bumping each other. I would post pics, but they are too fast! Lol! Would this behavior and the comb/wattles be enough to guestimate that these kids are cockerels? I know that when my flock leghorns were chicks they developed wattles and combs pretty big and red early on too so I am curious to know if this is a reliable method for this cross. Also, am I correct in assuming the mommas will soon be kicking the kids off?
