On Thursday I had 2 eggs that pipped. Friday morning I could hear chiring, All day Friday I could hear the first 2 chiring and had 4 more to pipped. Saturday morning around 1:30 I went to the bathroom but stopped on the way to check on the bator still nothing. Then while in the bathroom I heard loud chipping and it was sounding crazy. I ran back to the bedroom to find a chick inside the bator. I put it in the brooder and checked on the other 2 that was the first to pipped. They were very quite. I touch the one that had it's beak sticking out and it started to chir again. The one that had cracked 3/4 of the around didn't do anything. I removed the shell but it had died. Not wanting this to happen the the 2nd one, I helped it out of it's shell and membrane. It was very weak but now it's doing fine. My question is why were the first 2 having so much problems getting out when the 3rd and 4th one didn't, they came out like gangbusters.
