The cage sounds like a good idea. I bet your not the only person out there with that problem. please post the picture when you are done it, might give some others an idea how to do it. As for going hydro ruiner. You pick it up fast. Half to interst the other half due to repetition. thanks for your input.
Your optimism is encouraging, I'll work at it till I get it right. With help from communities like this I know it won't all be trial and error.
And I'd be happy to post some pics of the cage when I'm done, I'm not a carpenter by trade but what I have built should server its purpose to the fullest. A few more crossbeams, some heavy duty plastic chicken wire and a door later I'll be back with pics.
