That makes a lot of sense, Fisherlady. Thanks. I tried opening up the carrier again today, while the blocking off the door to the coop so that the other chickens wouldn't bother her. She didn't get off the nest, but I was able to see the chicks scramble out and eat and drink out of the dishes I had in the carrier. Mama called them back to the nest after a bit and they were able scramble back in without a problem. Maybe seeing them eat and drink has made mom feel less urgent about leaving her comfy nest. I have another BO who seems to be practicing going broody, so hopefully all this learning is going to be put to repeat use!
