We have a buff orp hen that just hatched out some chicks from a cuckoo marans roo. It looks like 3 are black with a bit of yellow and one is brownish and yellow. She just hatched them this morning so I don't want to disturb them too much as she has 2 more eggs to hatch. Can I sex the chicks from this match? We are really hoping for hens as we only have 2 left after the fox cleared out 6 chicks and a hen in june. If anyone has pictures of this match I would love to see them.
