For someone with plenty of time and just a few rabbits, there are a lot of different set ups that will work. However, if you need to spend your time on things other than scrubbing hutches and replacing bedding, the all wire cages are the way to go. Parasite control is the most important advantage. Put a pine board or a piece of sheet rock on the cage floor. If their feet get tired or bruised or if the wire gets too hot or cold, the rabbits will sit/lay on the board. Don't tie it down, they love to play with it. They will chew on it, which helps to keep their teeth trimmed down and in good shape. The calcium in the sheet rock is good for them. Just make sure it does NOT contain fiberglass. Keep extra boards, some rabbits will soil their boards. You will need to swap them out and clean them or you'll have the same problem you get with solid floors. If your raising Flemish Giants or Checkered Giants, you will need to use solid flooring. They are way too heavy for wire. Normal sized meat rabbits that constantly develop sore hocks, should be culled out. Buy your start up stock from an experienced commercial grower. They will have developed their strain of rabbits to handle the wire floor. You will have to develop your rabbits to meet your goals. You can start with show or pet type rabbits if you want to, but it will take you longer to develop a hardy strain. And again, rabbits love to play. We put yellow golf balls in the cages. We can hear them rolling the balls around in their cages all the way back at the house!
