normanack I'm sort of in the same position right now. I have one cockerel and two pullets hatched from Papa Brooder eggs, one of the pullets is half the size of the other but has begun to catch up. All three I feel are quite small, but they are only 3.5 months old and I have no idea whether/how growth will continue. I also have one little pullet that hatched 3 weeks ago from Blackbird13, chick down is lighter than the other two pullets were. I have a friend who lives about an hour away who has birds from GFF, she has offered me chicks next spring, and I am certain to take her up on it. Until then, I have what I have. I adore the ones I have. For his diminutive stature, the cockerel is quite full of himself and already calls his ladies over to the food dish when I refill it, and has been working on his crow since he was 7 weeks old. If the pullets are as precocious and begin laying early, then I will use them and try to increase size as I select future breeders - while trying to preserve type and precocity. This precocity harkens back to the leghorn influence, I believe.
I have thoroughly enjoyed the discussion and pictures of various barring and dilution influences, and look forward to where it all settles out on correct type and color for the standard
