These babies are about a week old. Even at this age, their coats are noticeably different than the normal coat - shorter and denser.
These Holland Lop babies (not my picture) are about 2 weeks old.
This is a 3-week old Mini Rex.
So is this. (Yep - my avatar)
Rex coats are unique from the get-go. Yeah, I'm not impressed with this breeder, either - she may know quite a bit about rabbit care, but she appears not to know diddly-squat about rabbit breeds. I'm sorry this happened to you.
I envy you going to the show - I haven't been able to get to one in
ages. Lots of breeders bring animals to sell to the shows, so you may find just what you want there. Certainly, you will find very helpful people and more information than you can process in a month . . . . everybody goes home from a show hoarse from "talking rabbit" all day (a friend of mine once said, "of course we do - nobody else wants to hear it!"). Good luck!
