Does anyone know of chickens that do not lay eggs? We live in AZ, so they have to be able to put up with the AZ heat. I plan to have a coop, but let them out for a large portion of the day to help keep down insects, etc that you have when you have horses. I just don't want them laying eggs all over the property, so something that either doesn't lay eggs and/or something that doesn't lay very many would be great. Any suggestions?
