Mrs. AK-Bird-Brain :
Definitely Coturnix. I had a pair of Texas A&Ms that would sleep in my hand, or sit in my lap.
Gambels are cool, but flighty.
And, if you're going to get them, may I suggest hatching eggs? The chicks are SO tiny, that shipping them will likely be very hard on them. The coturnix eggs do surprisingly well in shipping, too, and there are many different colors out there.
Cheap, too. After my bad hatch at the end of July, I said I wasn't going to gamble with shipped eggs again until the weather cooled off this fall ... then, I went on
ebay, and saw an auction that was going to expire in less than an hour for 60 coturnix eggs for $3.49, and there were no bids. So, for a grand total of about $15, I bought them. They hatched on Tuesday/Wednesday, and out of 55 that went into the incubator (5 damaged in shipping), I have 30 that hatched and all appear healthy. That's quite a bargain, IMO. They are a really big mix of colors and breeds, too, including some fancy ones. I've got 3 that I believe are "tuxedo" pattern.
