I've thought of a variety of ways to do it but have generally been stymied by the fact that my rabbits are not static. I move them from cage to cage frequently. I sell off older stock. I keep more younger stock than I need so I can grow them out. So having a name stuck to a cage seems fairly pointless.
For a while I used shower curtain rings with poker chips. They were colour coded by gender, as well has have a chip per half cup food eaten. I could easily move them from cage to cage AND the chips were easily replaced if I had to change out a name. VOILA! Thought my problem solved. Forgot to consider... some rabbits thought they were for tugging on (not so good for teeth). They rusted. The chips occasionally broke. Sometimes I couldn't reach the drill (hand press type) to make new chips so I got behind. NOT what I wanted at all.
So I did some more thinking.
When I rebuilt my cage I hung these metal things to each cage (actually my seven year old did that job).
I put a white envelope label on them and wrote on the name.
It didn't take long and...I ended up with this
So i was out in the store about a month ago and saw this
I snatched that up.
Went to the dollar store and found some small envelope labels.
Thought about it for a while, practiced with some labels to see what I wanted on them.
Decided on the following
name, month/year birth
Easy to replace.
Easy to make (son can help with cutting)
Easy peasy to put on.
I know at a glance which of the growers (the polish all look quite similar) is who and who they are from so I can watch my inbreeding coefficient. I can tell people when they come over how old certain rabbits are. It's just SO easy.
I'm pleased. Mind...today is the first day of having them so I'll have to give an update in a month or so to see how they hold up. But so far, I have high hopes.
They only thing I can't do is label the outside cages...need to think on that some further. I'd like something similar but just haven't gotten it figured yet.
