Nugget is now 5 weeks. Mom is an Isa Brown, Dad is Welsummer(pic added). We have two chicks from the same parents. The other one is only 3 weeks but they look nothing alike so I added a pic, merely for comparison. Nugget has a pretty impressive tail but, that comb looks pretty small, especially in comparison to the younger chicks/sibling. What do you think, is little Nugget a pullet or roo?
