I didn't candle, just chucked them as they were so cold. Mum has been out and about with her babies and was no longer sitting in the same spot the eggs were in. Only two chicks, one choc orp bantam and one pekin (it's either a red or lemon cuckoo). A couple of chicks had almost hatched but died.
I also have 6 pekin chicks indoors that I was going to put under Betty but I think I'll keep them inside due to how cold it's got today.
