I am going to be buying some egg laying hens in the spring. I have a lot more experience with bantams and fancy breeds than layers. I have already decided on white Leghorns and Americanas, although I am trying to decide on a brown egg laying breed. I have been looking at RIR's, Production Reds, and Sex Links. I haven't been able to find a lot of actual numbers on the amount of eggs that the hybrids produce compared to purebred RIR's, and everyone seems to have differing opinions. I know a lot of this has to do with how they are cared for too. I am just trying to figure out if there is anything that really stands out about one type over the other, and get opinions from someone who has owned a couple different types of these chickens. My main needs are for egg quantity, large egg size, and also a chicken that will lay well in the winter. I live in Washington State, and also live in a canyon that blocks a lot of sun light year round, and all of it for about three months in the winter. They will be receiving supplemental heat and light in the winter. The chickens will have to be cooped up because of wild predators and dogs in our area. I am not concerned with meat, and do not need a broody hen, just trying to find the best year round layer. Thank you very much for your time, and any info you can give me!
