I take the SOP as "form to function" In horses they have performance horses and halter horses in the "70's halter began it's journey to looks not function now we have performance halter where a horse must perform first to show in that class those horses are to me what we're looking for with the SOP. Sure there are chickens bred just for producing eggs and chickens bred just for meat they are not in the SOP. I want beautiful chickens that have an excellent rate of lay and the excess birds have enough flesh to butcher..that's why I picked the Delawares and the Rocks and so far I'm happy with my eggs and meat it's the breeding of them that I'm trying to learn. I'm learning more everyday thanks to the people on here who are willing to help show us. Thank you all very much for the help I've gotten so far I'm a sponge....
