here are the breed we thought we ordered:
Ameraucana = 2
Black australorp = 2
Rhode island red = 2
Rhode island blue = 2
White leghorn = 3
Noir marans = 1
Welsummer = 2
Speckled sussex = 1
Pictures 1 and 3 are your "Ameraucanas" (actually Easter Eggers.)
I think 2 and 5 are your Welsummers.
4 is either Black Australorp or Noir Marans, but I'm not sure which.
I can't see the comb or legs on the cockerel, but I'm leaning toward him being either Welsummer or Easter Egger.
Since you received 17 chicks but that list only has 15, either you missed a breed or there are extras of one kind or another, unless the hatchery included a mystery chick of another breed yet.
Which breeds have you already identified?
