Bird Netting and Snow
We have bird netting over the rabbit colony, to keep winged predators at bay. Some people think the netting will discourage raccoons and similar, but a raccoon will tear right through bird netting or even chicken wire. For them, we have electric scare wires. But for hawks and owls we have bird netting.
The first year we didn't have any problem with hawks and owls but the second year they all but decimated the colony in two or three nights. That's when we decided to put up bird netting. It worked beautifully.
After two or three years, the netting was getting old and tatty, all torn and fallen down in places. I kept thinking "I need to replace that netting..." but never quite got around to it. Then overnight I was down to four rabbits! When owls strike, they are effective. So I made a trip to the hardware store and got bird netting and put it up. Within a couple of weeks it snowed... and snowed... and snowed. And the bird netting fell down. I had strung it up on old clothes line that I ran up the middle of the colony from a gate post to a tree, and secured it to the fencing with regular old string. The weight of the snow was just too much.
This photo was taken in January. When the snow finally melted enough to dig the netting out, I re-hung it. It was down again within the week. It's been a trying winter in the rabbit colony. If/when we build another one I think we'll construct the "roof" of 2x4 or 4x4 welded wire on a wooden frame.
