I've never had a hen like that !!! I have hens in with my wife's cochins and silks . no issues. also good mamas and hatchers. im with boggy on all other .
I love mine but have cost me a lot of time and money I had to get birds shipped . I don't know how much you know about them but they do need a lot of room and sand floors in pens . also high perch's. boggy might be able to fix you up with some .
should have some around you some where need to go to local show you wheel find all you want . 3 weeks ago I went to a show and came home with 10 new birds . most came from NC.
Watch for those res genes pop up at any time . I second buying the books if you wanting to breed and show could save you years in breeding for rare colors and traits. Are find a good mentor.
Got the stud cock from a friend that had know idea of blood line. He is a cull. He is one that gets to free range he is good yard art. He is from birds that have the nmg .
