When I first started with laying hens, I had some Buff Orpingtons. I had gotten them through the Murry McMurry hatchery.
They laid lovely big eggs, light brown, almost a pink color. They didn't have the production I wanted though and they quit laying. They had a very gentle disposition, the children could catch them and pet them, no problem.
I switched to a hybrid brown egg layer.
Last summer I got chicks to raise for layers. I got Isa Browns and decided to get a 10 Buff Orpingtons for old time sake. These chickens came from a hatchery in Michigan. Most of these Buff Orpington are nasty & bad tempered, they'll peck at you and draw blood. My husband hates them. :runforhills: We got rid of most of the Buff Orpingtons, and kept the few that are gentle.
I don't know what the difference was between the two groups. Maybe one bunch was not purebred?
I've had New Hampshire Reds. They were nice chickens, didn't get as big as the Rhode Island Reds. Pretty too.
