I understand the stealth rabbitry, too... we keep as low-key as possible, too. There does not appear to be a specific limit on rabbits here. I'm over what I want to have, because I've had to retire a buck (but he's a pet), and a dwarf doe pet came with our third brood doe, which was given to us. So I have 6 adult, permanent rabbits, where I would like to have 4. But at least I have a good buck and three brood does now.
Anyway, we happen to live next door to the block captain, who appears to be a member of a local animal shelter. She came over shortly after we started building the rabbitry, and the kids excitedly pulled her into the back patio where our rabbits were temporarily housed. They were very crowded, and the setup was difficult to keep clean, and I was horrified that she had seen it. I immediately called her attention to the rabbitry we were building, and explained that they would shortly be enjoying new, spacious, clean quarters. I ordinarily would have avoided letting any of our neighbors know that we had rabbits. Then I made the mistake of asking her for some trimmings from her elm trees (which were being pruned) for the rabbits. She said that would be fine, I could have all I liked. Then she asked if we still had all the rabbits that she had seen before, and I said no, we were down to 4. Her curiosity was aroused, and she wanted to know did we sell them, give them away... what did we do with the other rabbits? Cornered, I finally admitted that we raise them for meat. She recoiled a little, and I quickly told her that I hoped I didn't offend her, that I don't want to cause trouble, that we had started this because of the economy and the prices of groceries going up while my husband's pay remained the same. She processed it all, and even said she might try some rabbit as long as I prepared it. I like her, she is very nice, but her being the block captain and involved with the shelter makes me worried that she will try to find a reason to get rid of the rabbits.
Sneaky is good. I wish she didn't know about them. It worries me.
