I have 15 chickens I chose just for laying( barred rocks, ee, rireds, black star, white rock, Brahma, giant) They are all different ages 5-8 months except the RIR she is 2 and quit laying. I've checked all the reasons for not laying and I don't think my birds fit any of those reasons I feed the purina layer with flock raiser, I clean the coops almost daily(i stay at home) dust them for mites,(never had mites), I fed them electrolytes once or twice in 2 weeks. I worm them(never had worms) they are happy hens that get along well, they have lots of space and have an enclosed run. I live in Florida no snow just decreased hours of sun. Today I gave them pepper and hoped for eggs! But nothing. I told them I'm giving you a week! If no eggs someone's getting sold. They all have RED combs and waddles. I guess they just don't wanna lay for me! I give them meal worms too. They are just hens that are on vacation ALL the time! Never saw an egg EVER Probably won't ever.
