Ditto that. Coyotes are skilled stealth killers. Please don't beat yourself up. You can't predict the first attack. I'm so sorry you lost 2 hens. Ditto dat too. Out here, we have packs of brazen coyotes and singles. I hear them screaming most every night. They hop fences and kill dogs and cats in subdivisions. My neighbors learned too late. 1 missing chicken, a few days passed, a few more, then the pack came in and killed the entire flock plus 8 turkeys and his chihuahua. They absolutely will case, then snatch a snack in broad daylight. ^^^X3 on electric fence. And a burro! Those buggars will stomp the dickens out of a predator. Geese? as an alarm? Coyote will be back. Hope he doesn't need to die from lead poisoning, but it is what it is to protect your flock. Best of luck, please keep us posted.
