I think you should be refunded your money if the chick you hatched was not the breed you bought.Who cares if it's one chick or 100 chicks? She advertized,you bought,you did not get what you paid for. It's as simple as that. If you had a 0% hatch,this post would not even exist. There is no excuse for sending something other than what you advertized without making it right.
I know you can alter a picture,but you can also send a different chick. If she knows you are lying because she knows she sent the right eggs,she would just tell you that. I only send marans eggs from marans that are no doubt purebred. If a hen got out,or a non-marans rooster accidently got in, I would not sell those eggs until I was sure they were pure,period. I can't guarantee much in the hatching process,but I can gaurantee that.If you were to buy my pure marans eggs and then claim you hatched a non-marans chick, I would politly but firmly tell you that there is no way that could happen. That's my opinion.
