Hopefully this works, I am trying to post pics.It really sounds like you have Easter Eggers and not Ameracaunas. There are sooo many people out there who sell EE's as AM's, some knowingly, and many unknowingly. You should post some pictures. There are many people in this thread who could tell you right away with good pictures. 99.9% of the time they're Easter Eggers. I've bought many. Luckily, I did not breed and sell them as Ameracaunas. EE's are great birds though, just need to know what you've got if you're going to breed.
If you want to find some true Ameracaunas (not that yours are not, I don't know) this website has a breeders directory along with the pictures and descriptions of the different varieties. You are much more likely to get true, quality AM's from someone on this list.

The girl on the right is my red layer. The two on the left are the ones in question. They recently had an encounter with a feral dog pack, so their tail feathers are missing, but they survived without any other injuries.
