I've process 20 of my A&M's this summer. Haven't seen a all white meat yet (nor do I really think there is enough meat to justify me processing any unless someone locally wants to pay me for my time)
With that being said, I tried to take the biggest, whitest, layingest, etcest and hatch 20 eggs this last summer. I must say that the 14 that survived the hatch are bigger and healthier than the parents were. I have gotten rid of the alot of the parent stock this past week but the 14 are now divided up in to 1 roo, 3 hens. We'll have to see what the next generation brings!
