I am only familiar with Julie's Charlie babies and her babies from Tubby. And can say, like Julie has, to really know what you got, you need to let them grow out till at least 7 to 8 months old. There was a few who told me at 4 months to cull all of her boys I hatched. And now the thought of even letting my Splash cockerel being taken off the property is outta the question. He is too nice and too valueable to me and to the rest of us who are trying to make some nice UKers. He went from ugly hatchling to the cockerel who fertilize my golden eggs from her Splash girl. Definitely expect changes leaning towards greatness. Be patient is what I say.
OFCOURSE I am talking with my only experince being Julie's babies. But, Joy has the same blood and more so running through their veins. Nice chicks!
