I noticed with both Smokey and Topsy that they moved away from the eggs that were not going to hatch when they had their new chicks. Pretty much by Day 25 they were done and would take the new chicks away from the old nest and start a new nest somewhere on the floor of the coop. It's so cute to watch how they show the the food and scold them for not listening.
Oh no, not a new nest?!
