Is it possible for the chicks to pipp them drown in their own egg fluids? The 3 that i had found dead had yolky crust around the pipp hole. Appears more as they drowned? The pipps were on the bottom side of the egg if that makes a difference. On a better not though....there are 9 chicks so far, 4 more almost hatched. I hear more peeping but no pipps yet. We're only day 21 now.
