3 of my 4 eggs hatched yesterday (Yay!!!!). All the chicks are fluffy and moving around great today, still in the incubator. The final egg has a pip but is progressing much slower than the previous hatchings. The paper towel I put on the bottom of the incubator is getting pretty gross looking, the last egg is getting pushed around quite a bit by the other 3 chicks, and they occasionally peck at it. I'm pretty sure I know the answer already, but should I still leave the 3 hatched chicks in until the final chick has been in the incubator for 24 hours? It's a Brinsea Mini Advance and with 3 chicks and an egg it's already pretty crowded in there. Could I remove the 2 oldest and leave the the newest hatch to keep the other one company? Or just leave it alone like I'm supposed to do and sit on my hands for another day?
