I raised dairy goats for years (until I had to rehome my last two prior to moving here to Colorado)...now I grew up in MN, but lived in AZ for a year, and now am in CO. In MN, alot of my 'cull' babies went for goat meat...not just 'religious' folks either, but normal people. AZ, you could find meat goat breeders anywhere, and everywhere...no specific breeds really, most were mixed, but goat meat is goat meat, as long as it is young, imo! Same here in Colorado, I see meat goat breeders selling meat goats often on craigslist. In all the states I've lived in, you can find goat meat in alot of supermarkets, they just may not have it in "all" the time. Same with Lamb. Some places around here though and back in MN you can find it anytime of year. I'm sure that is true for alot of states.
Now, I have no doubts in some of the more 'eastern' states, goat meat may not be as commonly found, I DO know several dairy goat breeders from out in the eastern states, and many of them will eat stock they won't use for breeding.
