OK I got a Australorp Roo, but his tail set is way to high. Almost if not a Squirrel tail. If I put him with hens with nice low tail sets will that help bring his offsprings tails down? Or will I just be breeding more Squirrel Tails?
It'll probably be a mix of both, and some somewhere in between. You should get a couple nice ones though!
Also, I've read in several places that they're recently learned that the chicks will take after the mother more than the father, so it's more important to have nice hens than nice roosters when it comes to breeding, so I think you'll be fine.
