A friend bought Ameraucana hatching eggs from Sunnyside up Micro Farm. Two of the chicks that hatched she gave to me. She thought they were 1 pullet and 1 roo since one is larger and has a pinker comb. Both birds still have completely flat combs though and while these are my first Am chicks, I've raised lots of EEs- and roos usally start developing their "pea" rows fairly quickly. Could they both be pullets?
