Ameracuana (no i)
Pure bred, buffs and beards, standard colors (reference the Ameracuana breeders club for list) must meet SOP for the breed to be concidered one. ONLY lays blue eggs.
Easter Eggers are a mixed red chicken which come from atleast one blue egg gene parent. They come in all colors and patterns with the most common being a game bird pattern of browns and yellow/gold. They can have beards, muffs, neither and typically have green legs although some can have slate colored legs. eE will lay brown, green, blue, olive eggs. Once an EE starts laying the egg color won't change, but might fade over time.
Olive Eggers are similar to above, except a blue egg gene chicken is crossed to a dark egg gene bird (typically Welsummer and marans) to create deep shades of olive shelled eggs.
I don't care what they call them, hatcheries and feed stores DON'T sell Ameracuana chickens. They can only be purchased from breeders.
