mmmm -- the dark chicks from this hatchery stock, usually wind up being cockerels ....
but we will wait and see
you have some of Phoebe's eggs in your mix (pointed end pale green ones) -- and she has a mostly-black head ... while this chick may not have inherited the Columbian genes that many EEs carry, so could come out all or mostly black !
might be interesting to see if you can scrounge the eggshell out, I had most of the eggs marked in pencil, as to whose they were as well as the day they were laid
your olive-drab eggs are from Becky, the pastel greenish ones from Phoebe (pointed), Anitra (medium), and Christina (large)
we already know one of Christina's was a real stinker
Deirdre lays the pale turquoise blue ones, Ginger lays pink (and hers are usually so small I'm not sure a chick would hatch)
