about 2 months ago I purchased 3 hens, two marans and one silkie. They are now intergrated with my flow and getting along fine but no eggs from them. I also had 3 easter eggs and one bantam in the original flock who were laying an egg a day. Now the only one laying is the bantam and she lays an egg everyday (one day she laid 2). I know it is getting late in the year and I figured they would slow down but not just stop completely. should I be worried?
