Kuntrygirl,you can add them onto the cages you already have, just get some 1/2"x1" wire and add it to the bottom, after you cut the bottom hole in the cages and fold back the rough edges under. If I can do it, you can too! And you know you can ! I use some 16"x16" ceramic floor tiles inside in the summer to help keep the rabbits cool. In the winter, you can either turn the tiles over to the unglazed side or use wood which is warmer. The tiles are easy to keep clean and when it gets really hot, I rinse them in ice water to cool them off and replace them into the cages. I also save gallon jugs and 2 liter bottles and in the summer fill them with water and freeze them. When it's getting into the 95 degree range, I put these frozen ice jugs into the cages to keep the rabbits cool, and change them out as needed, wash the outside and refreeze. I also use frozen jugs to keep the brine on the turkeys cold, while they go through rigger. They last longer than cubes and don't cost anything! I also put some ice into their water jugs in the summer, but will be putting in water tubing and drinking nipples as soon as I get all of my cages finished and the barn rearranges. I only have 28 rabbit holes now and will be adding 26 more, for the add'l does and mini Rex's. The water system will go to a box that has a float valve in it, to reduce the pressure going to the nipples to gravity feed and I will add anything I want in their water like ACV, meds or ice. What size cages are your Flemish Giants in? What size for smaller breeds? What size nest boxes do you use for smaller size breeds?
My rabbits also enjoy a cold cucumber or melon on a hot day, so I plant a couple extra vines of cukes in the garden. Does anyone else out there also raise rabbits, in Louisiana and what breeds?
I'm not sure if I can do that Celie. I think that you're a little more advanced than I am. I have been spoiled over the years, so when I want something built, I just put on my sad puppy dog face, look at "my builder" and bat my eyes and look like I'm pitiful and within no time, it's built.
Maybe I can practice my puppy dog face and send him these instructions and see what happens. I think I better wait until after I get that plucker built. 
I have used the frozen jugs for the chickens in the summer but never thought about it for the rabbits. I will definitely try that this summer. Thanks for the tip.
I'll have to check on the sizes of my cages. The old man that I mentioned builds them, so I just call him and tell him I need another cage and he already knows what I use, so I don't give him any measurements. I will measure this weekend and let you know.
I use the same nesting boxes for all of the breeds. It seems to work. The boxes are kinda big, so it fits the small and large breeds.
Now you got me all excited about future rabbits.
Sounds like you have some VERY lucky rabbits over there.
, I like that one!
