The quail are indeed a viable alternative to chickens for small scenarios, hell even big scenarios these could be a great route to take for a prepper I know mine are. I've mentioned the ability to keep them indoors because of their cleanliness and that they are cheaper, but they are also cold hardy and just a simple easy alternative to chickens.
I've been eating the eggs, replacement for eggs check. They taste better and have all good cholesterol, you get about a teaspoon sized sunny side up. Made batter with it tonight. Much more gourmet than chicken I think and they fluff up and hold air well. You need to open them with a sharp knife, easy enough with a learning curve of 5 or so.
So the incubator build, what to say. It worked. It worked way way better than I thought. I have 22 chicks as of now and probably will see most of the remainder hatch. There's a lot of eggs in there still. I lost three chicks to the water bowl inside, dont understand how they managed to climb it but they went in. Then all the others started coming. 4, 3, 2, 2, 4, 3 just pumping them out. two are in there now pipping the shells so here come nightfall I am betting on seeing a few more before I hit the sack. So I've effectively doubled the size of my flock (covey) for almost no money in a turnover of around 19 days. In a month and a half, by the time summer is here, they'll be grown. That's impressive. I did lose one to a cooper's hawk, it stuck it's head out and the hawk grabbed it and killed it before I shood it off. BUT luckily now I have another possibly 20-30 to chose from for a replacement. I think I'll pack as many into the main population pens as I can and build some more space.
