Oh, I don't know... everyone has their own opinions. I only do it once or twice just to make sure that they're growing. I don't want any duds exploding in there... ick!
I can barely tell if there's growth at seven days simply because I don't know exactly what I'm seeing. If I'm sure of what I see at seven, I don't candle again, but if I don't know I'll candle again at 12 days.
I just bought a bantam cochin roo and hen... I'm hoping they'll learn to get along and give me a few eggs to incubate as well!
