As far as I know. I got them from Murray McMurray
I haven't ordered chicks from them so I can't say if that's normal for them or not. I do know they send a free exotic, which is almost always a roosters, so that's probably what the last one is if you didn't order it.I feel like I got several kinds of chicks that I didn’t order
You could contact them if you think you didn't get the correct birds. They should be willing to work it out.
