Wow ! Where did you find that teeny collie? Very cute.
My experience with mixing predators with bunnies and poultry is mixed...
Two bunnies killed , a dozen chicks eliminated, a pet cat disappeared, and two Muscovy ducks snatched up most recently.
The chicks were victims of a pair of Turkey vultures, but the rest were all from a nearby family of coyotes.
So the coyotes took the rabbits as easily as they did the ducks.
Get yourself some good fencing and a 20 GA and don't rely on bunnies for protection.
( 20GA has less kick than a 12GA and not so much noise to alert neighbors. )
And... as for using pigs as guard animals- anything that can kill and consume a rattlesnake with no ill affects
would probably look at chickens as snacks.
Lets hear from some of you homesteaders--- ever lose hens or poultry to a hungry porker??????
