I have silkies right now. They free range in a 1 acre fenced area and have a horse loafing shed that has been converted into a large coop that they can come and go from as they please. I want to get about 4 standard size hens that will be good layers. My silkies all think they have to be moms ALL the time I live in the dry desert and the summers get very hot, the winters are very mild. I do not have experience with other breeds and I need one that can handle our weather, not be too aggressive with my silkies, and be good layers. Can anyone please help me with choosing the right breed? Thanks!
