She's supposed to be a buff orpington. Obviously not. She is 5 months old. I don't see any starter crom or waddles like I do on my other girls (buff orp, leghorns, barred rocks, RIR, NH red)
She is a white easter egger/ameraucana. Those puffy cheeks and beard give it away and the tiny comb, lack of waddles and feathering mean she's a pullet for sure. Might not be what you thought but I think that blue eggs would be a pleasant surprise.
