They were bred by the A&M University for meat.
They are very easy to raise! The chicks need a 24% (or better) Gamebird Starter (GBS) and fresh water available at all times, I also like to put marbles in the waterer to prevent drowning. Also, if you keep them on ground, you will have to deworm them with pumpkins or Wazine 17. Incubation period is 17-18 days. Keeping them on wire is better for them They weigh about 14 oz. at maturity. They have an awesome temperament, and are bred for meat and eggs. They have an awesome temperment! They make great pets, and can sometimes be house pets also!
For another person these may have been the best things ever. I personally got them as pets, as I wanted quail and knew nothing about the breeds. I got them at 2 weeks old. They were stupid. They'd get stuck everywhere and in everything. By the time they were 10 weeks old three of my 10 died from stupid self inflicted accidents and I finally got everything to the point that they could no longer hurt themselves on everything. The up side to the stupidity is that they don't fear people very much. The downside to that is that they'd fly out to perch on me whenever I opened the run to water them. I lost one of these to a dog when he flew out while my sister was feeding them. They aren't smart at all.
Let me just say that when people say they are large, they aren't lying. I've had several breeds since these guys and they were by far the largest.
They were extremely difficult to sex as I could never tell them apart, so one minute I would know who the one making the "boy" sound was, then the next second he would disappear into the group. All I know for sure is that there were at least 2. They were very quiet. Never went off crying like some breeds and the males were more quiet that my quietest chickens.
Since they were intended for pets I didn't really bother with setting up a cage I could find eggs in easily, but I never found any.
At the end with these guys, I decided that I just didn't enjoy them and moved full time to my chickens and ducks. I traded the remaining seven for three chicken hens. While I had them in the cage ready to leave, I look in, and tada! an egg. So they were laying after all! Nonetheless, I continued on with the trade. The woman I traded with was moving and could no longer keep chickens, but still wanted the experiences that came with chickens for her kids. She later told me that her quail were perfect for her. They were kept inside with no problems.
The egg that I did get was massive compared to what I was expecting. I did eat it and it tasted no different than a chicken egg. I like to call it my $100 egg, as that is probably the un-reciprocated cost that went into them.
I would suggest them for the not-a-chicken-but-I-want-chickens lifestyle, but not as I kept them. I did like them, they just weren't for me.
