Well so far so good. My lovely husband took it out and put it in the brooder while I was at work (he was yelled at) I had another pip after that. They were not all set on the same day. 2 where set one day 1 a few days later and 2 a few days after that. I was mostly just checking for fertility. Only 1 of them sosnt take. Well that I know of. 3 are olive egger eggs and I can't tell if they are still good. I ordered a stronger candler. I saw some veining in the beginning but now I can't see anything but the air sac..thanks for all your help!!
