Here is a chick I bought at a partridge rock pullet. I bought two of them and one developed slow and the other fast. I thought great one girl, one boy assuming the boy was the slow one to develop.
Here is a 4 week old partridge rock. As you can see he is all roo. Lets hope the other once continues without color, or size to her comb.
Look at that comb and waddles already at 4 weeks.
He surely passed the testosterone challenge.
