I guess it doesn't matter very much, but a couple of my new chicks appear to have some black spangling on them. Pretty cool, I thought. Anybody else have this happen? If so, what do they grow out like? Will I have chickens with patches of dark pinfeathers or mottled colored skin when I butcher? This is definitely the actual coloring on the chicks, not debris or poo stuck to them. Chicks came from my feed store, feed store got them from Privet hatchery. Anyone?
