Very new to having a rooster, one chick hatched yesterday and mama stayed on the nest but two didn’t make it as well as one that didn’t make it this morning. Mama’s left the nest now and so has baby, they’re sitting in a corner of the run. I have one egg that is cracked and the chick is still alive but quiet. Should I put her underneath mama in her new spot, or under a heat lamp, or do something else? I don’t have an incubator. Thanks, sorry for the noob questions.
