I got my 6 hens on Saturday and only one of them is laying eggs - one a day. could this be stress from the move? they are all eating well and moving about, seem to be "okay". the pen we keep them in is a lot smaller than they are used to - they had free range where they came from. we live in town so have to keep them in a pen, but it's about 18 x 18, complete with coop and all....we also clipped their wings so they couldn't fly out of the pen - doesn't have a top on it. any ideas?
