Awesome bunch of info.... I appreciate all of that. Can anyone give me an idea of how many cages I'll need in all if I'm only raising rabbits for my family (not trying to sell or anything)? Am I good with 4... a buck cage, 2 doe cages, and a grow-out cage? Or should I plan on adding more doe cages and grow out cages? The firewood shed is small (3' deep x 10 feet long)... but if I need more room I could add a covered area on the back of my shed (30' long) that would be open on 3 sides so they'd have shade and air movement or I could frame something up inside the hoophouse (12' x 40') to give them a solid roof and build stands.
Additionally.... when it comes to building cages - I see that buying cages from KW cages (just the first place I found, I'm wide open to recommendations) cost a range of $40-$100 (size dependent). They come disassembled so I'd still have to put them together. Is it substantially less expensive to build cages? I feel like I'd spend nearly that to build them.... but I'm not a carpenter and am not fast at building...and don't really know how much materials would cost.
I've been watching CL for used cages, but not having any luck and don't want to buy something that I'll regret later anyway.
Unless you have better wire options locally than I have, it's easier and more economical to buy the three initial cages you'll need. (Two does & a buck) You can get by with one doe, but you'll be out of business in the cold months I think (or maybe you're not as cold there as I am), and two does doubles the summer productivity. I got mine here:
Rabbit Cages - Rabbit Cage - KW Cages - Everything for Rabbits but definitely shop around. They come in a flat box and you put them together, so be sure to also order j-clip pliers & j-clips if they're not included. (They're cheap & easy to use. Amazon or your feed or hardware store.)
You can also find websites offering large quantities of cage wire. This didn't work for me, as I only wanted three cages. I didn't find anyone selling less than a full roll. If you wanted to get into rabbits in a big way though, that's the way to go, especially if you can get a lumberyard or feed store to order it from one of their suppliers for you, so you're not stuck with shipping costs.
I made a couple of chicken "tractors" into mobile rabbit cages. Well, semi-mobile. The one (a Suskovich tractor) is pretty big. I stapled (with a pneumatic stapler) 2X4" wire onto the bottoms to adapt it to bunnies. The other was for chicks. It's a decent size for grow-outs, but I'm gonna modify a second Suskivich as a girls' growout apartment. (They're currently in the "chick" tractor and getting a bit cramped. Time to process.)
The does need big cages, but the breeding buck(s) need smaller cages, not only b/c they don't have to share with babies, but also, breeding just goes smoother that way. (You always bring the doe to the buck, as she may get agressive if you bring him into her space.) When the doe decides to play hard-to-get, the buck doesn't have to chase as hard in his smaller cage. My 2 does have 30x36" cages and the buck is in a 24x24" one. If you have access to purchase actual meat rabbits, you might want to go bigger, but be sure to center the door to improve your reach.
I don't know whether anyone sells grow-out cages. I just have these tractors I made for my poultry (who all sleep in the barn now and free range... much easier, unless you have a high predator load). They work great for the buns so far, and I can walk into them. (If you're curious, you can find Suskovich tractor videos on Youtube.) The ladies will need nesting boxes. I made my own, with wire floors, but you can buy them. I haven't seen them here, but I think they have them at the link I put above. They're pricey, imo, which is why I made my own.
You also need waterers: bowls (I use galvanized clip-ons) for winter & water bottles and/or bowls for summer. I use the J-shaped feeders; medium-sized for breeding cages; large for grow-outs. I think a small feeder would've been a better choice for the buck, though. He doesn't go through the feed like a mom & babies, and I might not fill it up above once a week. (He's a bun who only eats what he needs.)
I give them sticks (mostly pine as that's what we have) to chew on (never give them cherry wood) and in the growing season, lots of yummy weeds. You can give them minerals, but that's incl with commercial foods and also included in yummy weeds.
Congrats on your new endeavor and have fun!
