I just brought home three new hens all just a year old who have been laying fine where I got them but they haven't laid for me yet. I got them on Monday. I have two buff orpingtons and one lavender orpington. I've gotten other chickens from other flocks and they've always laid at least the next day. What gives? Do you think they prefer hay than straw or is there something else I'm missing? They're acting like chickens so not traumatized or anything lol.
