Mine seem to be the opposite. Most predators can’t catch my smaller gamefowl and American game bantams. They’re too light and fast and fly too well. I don’t think any 4 legged predator has ever been successful catching them. Most hawks can’t either. The only hawk that got good at catching them was a particular Sharp Shinned hawk who practiced on them for months. And even then the sharp shinned would make multiple runs on them a day but only successfully kill one adult a month.
