I have ordered from two different people:
from the leghorn page:
Rick Sumner, he has homozygous for rose comb dark browns and white... some of his other rose comb colors are heterozygous for rose comb.
His egg packaging is WONDERFUL, he doesn't double box, but he did use the pipe foam insulation, very nice, none were cracked
from the brown leghorn page I ordered from Fred Zillich (much less expensive than Sumner), I got his dark browns and his whites. (both RC)
I only got 3 of his whites to hatch, all three were rose comb... but I never asked him if they are hetero or homo for rose comb. One of the whites hatched with 3 black feathers, but they are very pretty birds (form, etc. also production and maturity rate)
I had a better hatch rate with his dark brown rose combs, which ARE hetero for rose comb, but their color and body/form etc. etc. are very nice. They definitely mature more slowly than his RC whites. Actually, of the maybe 9 I got to reach adulthood, only one had a single comb.
I didn't like the packing job that Zillich did.... it was OK, and I got a good number to hatch... but, there we are.
I REALLY like the body shape/color/ etc on the Zillich RC dark browns... I am not happy with the rose comb on the rooster I decided to keep, and it turns out he is also heterozygous for rose comb, which upset me with the chicks.. (I wanted to breed only RC chicks)
Oh, the Zillich dark browns are WAY more wild than his whites.
Sumner's eggs are still 'cooking', I bought Zillich's eggs last year.
