I haven't seen a Jersey Giant around here worth spending feed on, far too slow growing and far too thin in body type. The show quality Australorpes would be a far better choice in these parts, they are almost as large as the Giants, grow much faster, and have a respectable amount of meat on them. I've never seen a quality Delaware, although I have read about a quality line in the US. Don't let the name fool you, my ameraucanas are nothing like any ameraucanas you have seen. I didn't build them from any existing lines, I felt the existing lines were built wrong, and therefore built from scratch using a hatchery ameraucana hen, a couple select araucanas, and some Rapanui stock. The bird to the left that I'm holding spent much of his life between 8 and 9 pounds and won his fair share of AOSB championships.
The Sassos were sold by the hatchery as x431b. Seems to be the preferred cross found in North America. Locally, they were imported to be grown in wharehouses, harvested skinny, and sold to the ethnic community as Thai chicken.
Not sure if I linked to the video properly, but the birds are the offspring of the x431b Sassos. Legally speaking, they are not Sasso anymore so I simply market them as French Meatbirds. If the link doesn't work, just go to my facebook page, I've got a few photos on it.
