What is pipping? I'm hatching my very first batch in Miss Prissy's incubator and I put them in on Thusday morning 7/31. Tonight as I was turning them I saw 3 eggs cracked! One has a pea size hole and is chirping. Is this too early?? My temps have been up and down lately and so has my humidity so I'm worried I might have cooked them to coming out too early?? I thought they were due Thursday. I have a medley from Bantams to ducks (which I know take longer). The old man down the road gave me a nice bunch.
