those are not blue ears
those are white ears. Minorca that isn't an Andaulusian comb we have raised both here.They are very small birds especially when they come from hatcheries..breeder Minorca's tend to be much larger.At 22 weeks she may be squatting but she's not done growing..she will spurt nearly overnight.Many hens even though they are laying are not done growing..for instance our BLRW take 18 months to reach maturity..thankfully not that long to start laying eggs
Minorca's are super layers one of the best we have had here other than our white leghorns..and no she's not a mutt
