**Half the peas that something chewed down outside came back. **
If you think the chewing is coming from a mammal, [squirrel. chipmunk, etc]....try hanging out a bar of Irish Spring soap in an old onion bag; or even shavings of the bar will work too. I’ve had great luck with the DIY hack on my bird/suet feeders, to keep the squirrels at bay.

Wrapping the fence with poultry netting seems to have done the trick so I’m pretty sure it was a rabbit.
