The 3 keets with a wide center head stripe are Buff Dundottes (fully-pealed), the one of the right with broken head stripes is a Buff (partially-pearled).
All 4 keets in that pic are tan gene based, not blue gene based. As they grow feathers, the shafts (under the wings) will be a pale cream color, not a light grey/blue color.
Oops, I just realized I hadn't posted the pic of my last keet hatch... and I do mean LAST keet hatch, lol. I won't let myself set any more Guinea eggs this season. My brooders and grow out pens are at maximum capacity with all the keets I am keeping, plus all of the poults, peachicks and silkie/showgirl chicks that I won't part with, lol.
Done with hatching keets for the year tho, whew.
