Ok - still getting used to difference between Muscovy and chickens, but - Marge JUST hatched these babies yesterday and this morning when I opened the nest box (I had hardware cloth across it, so no one would fall out in the night) - she got out , ate, drank, and then flew straaight up and ouyt of the dog kennel. Took a bath, was preening, half an houyr later I just now tossed her back in! babies are huddled and it is about 40 degrees out... should I worry? and at what point should I worry?
