I think it may be a mixed breed.
Its face and head shape looks like a Sumatra pullet, put the way the tail is carried so upright doesn't match a sumatra.
I got it from Mc Murray's the hatchery. Sorry I meant hatchery not breeder. And I've looked through their breeds but at this point it doesn't really look like any of them haha
It doesn't fit for any pure breed McMurray sells, so likely a hybrid. 'Ameraucana' maybe. McMurray's Ameraucanas are Easter eggers and can look like anything, just about.
