Hello I'm trying to find out if the first chickens to hatch in the incubator disturb the unhatched chickens when they are bouncing around and trying to stabilize themselves. I use a fifty egg incubator and at most I get thirty eggs so the new chicks have lots of room to move and they seem to bump the other eggs around a lot, will this reduce my success rate or does it not matter to the unhatched eggs to be rocked and bumped. thank you
