I have five nice little mixed breed hens and their hatch mate brother. Got them a year and a half ago at age 3 days, with their mom who has since passed away. The young girls layed quite well last summer, dropped off as the days grew short, which I expected, but have not returned to regular cycle. We feed them top quality layer feed, let them run all day on our two acres of garden and woods, keep them locked up safe and clean at night in a spacious coop with three nesting boxes, in which they enjoy a nice sit, but only the occasional egg appears. We have searched under bushes, etc, in all their hangouts. no eggs or signs of stollen eggs. We get about ten eggs a week out of five chickens. Two or three of those will be robin egg size-- and color. (the chicks were from a silkie mom with who knows who for a dad on the farm next door.) any insights? two of them also went broody last summer and now they are all out in the yard every day. I was hoping to let them reproduce, but it's not happening!
