Hi! I was hoping someone might help me out here. I have several RIR hens, one hen was laying during the summer months, then all of a sudden stopped laying. The other three hens never layed a single egg, the hens are now 11 months old. We live in south central Florida, the nights have been getting down in the 20's and days are usually in the 50's. Two of my RIR have started laying an egg every day. My chickens are set up in pens with no heat or lights, each pen has three hens and one roo. I am confused, from what I understood chickens stop laying during the short cold days. Has anyone every heard of a hen start laying in the winter months? All of my chickens are fed Purina Layena, using free feeders. Should I worry about the eggs freezing or should I get heat lights? Only problem I have with getting heat lights would be that the pens are too far from a power outlet. Any ideas or help would be appreciated.
