Hi everyone! Another Newbey here. I have 1 polish hen and 6 Orpington hens. All of my chickens are 6 months old except two of my orpingtons. They are just over a year and I accuired them a week ago from a friend who was trying to thin out her flock. They were laying great at her farm but since I've had them I've only gotten one egg the next day and nothing since. Any ideas?
