Hi, 6 of my eggs hatched last weekend. I do believe I have 4 buff orpington/black sumatra mix. They are very chocolately brown. The only other option is buff orp/light brahma, but they have no feathers or fluff on thier feet. So my question is..when do brahmas show signs of feet fluff? They have brown legs and feet. I believe the other two, with black beaks are black australorp/sumatra.
