A few quail questions from a newbie in need!

I don't know anything about raising quail, but I do know that plastic sheeting over the kennel will collect water if you lay it flat. I learned that from experience. lol. I am still in need of a good roof on my dog kennel duck pen.

 

Hi there, and welcome to the wonderful world of quail raising. Your babies are going to LOVE living in an aviary.

For the coturnix (and jumbo, which are just a large strain of coturnix), the dog igloos and lean-tos will be plenty of shelter. They'll take themselves out of the weather when they need to. I like to give mine a variety of separate shelters to choose from, especially because they will boss each other around, and I want even the low man on the totem pole to have a safe place to be.

Tin under the aviary will be fine, though I'd prefer wire for drainage & to let critters (bugs and such) enter the pen for the quail to eat.

As for the number, it depends on what you want to accomplish. Because mine are mostly pets and I enjoy giving them as natural a setting as possible, I keep my population to about six or seven birds per 100 sq ft (i.e., 10 x 10 pen). You could go MUCH higher than that successfully. Or you can balance production with comfort and choose a number in between. Things to consider:

• Larger populations require more work. They'll poop and pee more, requiring more frequent cleanings. With a population as small as mine, I never have to clean--nature does the work for me. With larger populations, a deep litter bed is a great choice, and you'll add more straw for larger populations (because you need more carbon material to help the pee and poop decompose more quickly). I like deep litter for quail and chickens, because it attracts ground insects that make excellent fodder for the birds.
• Never pack them closer than 1 bird per 1 square foot of space.
• The closer you get to the upper limit, the more signs of stress you'll start to see, and the more challenges you'll face. If you start to see either of these signs, you've gone too high: Females with the feathers plucked off the backs of their heads; fighting to the point of injury. Other signs of stress that indicate you're reaching your upper limit: Birds that are excessively flighty, easily frightened, or that injure themselves jumping up in a startle reflex.
• The lower your population limit, and the more enriched the environment (plentiful shelter opportunities, bugs to peck for, dust bathing opportunities, low brush to hide in, occasional fun treats like bird seed tossed on the ground to pick at, etc.), the more relaxed and comfortable your birds will be. Signs of relaxed birds: No sudden upward leaping, may come running to the gate to greet you if you regularly bring treats, full, healthy coats of feathers, plentiful egg laying, low energy (i.e., they'll spend large portions of the day just lazing around--this is normal prey behavior for a bird that survives by laying low, camouflaged in the brush, and only getting up to eat and breed).

I recommend starting with a small population and working your way up until you reach a level that is comfortable. Be careful when adding birds to never ever add adolescents (even full-sized birds can be sexually immature--and they can tell the difference in each other) to an adult population. They will get beaten up. Don't know why that is, but I can only assume that quail, like humans, find teenagers to be excessively annoying.
