does anyone know of any good reasons why my silkies aren't laying anymore. I have 18 hens and not 1 egg. They have been wormed. They have a heat lamp. None of them act sick. Not sure why I am not getting any eggs. Do SQ silkies lay less eggs or stop laying when it gets cold. When I had PQ silkies they layed all year. I sold all of them and have only SQ now and now no eggs. Please does anyone know of a solution to this.
