That's what I believe so I'm trying it now so far all my pullets are excellent layers and the excess roos I've processed are good too this is my chance to show people that you don't need hatchery birds they are too small as the first thing out of everybody's lips is wow those are some big chickens what do you feed them..... I just need a little better NH stock but it isn't all hatchery I don't know if I want to breed NHs I like my Rocks and Dellies and Marans
