Hi, I am considering placing an order with My Pet Chicken, but before I do, I want to make sure I am not going to make any of my new birds suffer. I am considering a standard Cochin (blue) and a Buff Orpington. I think they're gorgoeus. What I am worried about is they seem the have such heavy fearthering, will they be able to handle the heat in the summer? I live outside Dallas and summers can get a bit warm. I am also wanting to get some Easter Eggers, a Plymouth Rock and a Sussex. I know the PR and the EE's can handle it, I have some now, but the others I worry about. Any opinions before I place my order? Thanks!
