Thanks , yes two beautiful hens ! And pretty spunky already , they are funny .
I have had chickens and ive had a red before and i can state that everytime she got picked on she recovered great & layed good eggs . Ive had chickens in past and it has been a love ever since also pekin ducks whose eggs were great . I just have a passion of animals
