Ok. First sign of a predator around 5:00am today... Heard a strange sound coming from my backyard and knew it was not a chicken. On closer inspection I saw a predator. Ran downstairs, went outside to find 2 raccoons(both rather small-about cat size or slightly bigger). One watching, the other retreating head first down the outside of the run on the 2"x4" metal fencing. Had I not gotten there in time, there was a place for it to get inside. I will fix that this evening. Questions: 1. Once raccoons know about your chickens, will they be relentless and continue coming back and back and back...? 2. Do they eat chickens? 3. Had this raccoon gotten in what would have happened? Would it have killed al 5 of my full grown hens? Any feedback regarding coon behavior and solutions appreciated! Thanks!
