Interesting. I've finally settled down about hatching after 2 years. It is exciting, isn't it?I noticed that the earlier chicks rampage thru the incubator and kick all the eggs around. Then some of the eggs pip in the middle, or eggs that pipped never finish because the chick gets shifted in the shell from the rolling. So I started lining my eggs up in channels of shelf liner to keep them from getting punted all over.
I just put these in lockdown yesterday, the eggs really only go side to side, and the little channels prevent tgat
My first hatch I had no shelf liner at all, and those eggs flew around and hit the sides hard! I had several that pipped in the middle and died in the shell. Since I started doing this, I rarely have any who pip in the wrong place.
I'm getting decent hatches letting them do their own thing and play soccer with the unhatched litter mates. They do push them to the edges. When you say pip in the middle, are you talking about the widest part around the egg?
