My youngest daughter and I bought 6 hens from the local sale last Saturday. It has been 5 days now and not an egg, not even a hen pretending to. These are our first chickens and obviously we don't know what were doing. All but one seem to be healthy and vibrant. What gives? Any help is truly appreciated. We have 2 black star, 1 red star, 1 deleware, 1 buff orpington (she's the one with the long nails, I mean long nails and gets pecked at, she isolates herself), and what I think to be a cinnamon cubalya?
