I have 2 older welsummer pullets, plus 2 welsummer chicks (6/7 wks old)... The one chick got random feathers growing on top of it's head so I named it Top Hat. The colours are completely different from the other chick and my 2 older pullets... could it be a cockerel or what??? (I know the water dish is empty, my youngest plays with it lol)
