anybody keep chickens ?

I have Silver Penciled Rocks and my wife has her own which are Buff Orphingtons from show stock. Her buffs are to big for my liking. They roost and nest of the coop floor ss because they are to big to get up on the roost. Birds that big are not very hardy i wouldn't think. I like my silver rocks. They too meet the S.O.P. criteria and are bigger than most birds but can still roost and nest in the nest boxes. We generally have 12 hens in all and 2 roosters. We plan for spring and hatch out around 50 chicks in preperation for all the grasshoppers. Broody hens are allowed to brood and raise chicks too in addition to the 50 we normally put in the encubator for spring and summer grasshoppers. We process all the young birds when they get big enough/old enough. Might keep the best hen or roo out of the bunch and process a bird o deem less desirable than the young bird. We don't show chickens but like to have S.O.P. birds running around in the yard.
I let my hog dogs run around loose sometimes and they don't bother the chickens. Now and then a few hens will get in the dog pens and forge around. Dogs pay them no mind thankfully!
