I'm wondering if anyone could help me determined whether my Pekin (Cochin bantam) chicks are lavender or cuckoo lavender. Their parents are lavender cockerel over a lavender cuckoo hen. I tried the chicken calculator and from that it told me that the males would be cuckoo and the females plain lavender, is that correct? They are all silvery, some do have a paler almost yellow spot on the back of their head and a similar colour on the wings. I will try to get some good pictures later on today, they hatched yesterday and after having a brief power cut this morning I'm trying to keep them warm!
