Welcome to BYC! Glad you decided to join our flock. I agree with TwoCrows, you should post your birds on our What Breed or Gender is This? section for positively identifying your breeds. Your Orpingtons are actually Production Reds, the black and brown bird in both the top and bottom picture is an Easter Egger, and your white chickens with the black feathers on the necks appear to be Delawares (although I can't see them completely to be absolutely sure). These are all hardy, dependable, good laying breeds, although evidently not what you thought your were getting (at least in the case of the Production Reds). Please feel free to ask any questions you may have. We are here to help in any way we can. Good luck with your flock.
