My flock is now 26 months old, & have gone on an EGG LAYING STRIKE!!! Nary one teenie tiny egg in almost 2 weeks!! Almost as if someone has flipped a shutoff switch! This is deplorable (on my part) & even my roo sounds like he has a sore throat. My hens & the roo have been losing feathers all summer, & the bare spots show up VERY RED flesh color. We are located in the Mohave desert area. The weather is slowly changing to the cool part, but has not been drastic. I have dusted for mites, made sure the coop is clean, & everything else I can think of. Locals are telling me "it's the weather" but I tend to discount this answer. They even went through a period where the eggs were not staying firm in the skillet, but this has since passed. Any ideas or help out here???
