I love my sex links too. I do sell my eggs but I only make enough to feed them. I will never re-coup all of the money spent on the coops, feeders, etc. I live in Florida and we had wicked heat last summer too but there were parts of the country that were worse off than we were. I put a couple of sprinklers in my pens. The water wets the ground and they loved scratching in the cool wet dirt. I do have shade for the birds.
