We lost all 100+ of our chickens due to daytime hunting raccoons. We've had chickens for 4 yrs, and this was a first for us. The chickens have autodoors to enter wooden coops at night, so night-time is never a problem for us losing chickens, but first we had a bobcat, foxes, and hawks taking the chickens in daytime (originally free ranged) but then we built huge runs for each coop (5 ft high, roughly 50 ft by 30 ft for each coop), and covered the runs with netting to protect from hawks. All was well for about 2 yrs with that setup, but then the daytime raccoons wiped us out within a few month period. We caught them on camera so I'm positive it was the raccoons, often between 9am and 12 noon. My husband doesn't want to get a dog to protect the chickens, so I guess we'll have to resort to small runs that are raccoon proof outside each of the wooden night-time coops. I'm sad though because my original vision was of our lucky free range chickens we had when all this started. If I can only give them a smaller outdoor space (or do the chicken tractor idea), I''m not really sure if I even want to keep chickens any more. I guess it's still better than the chickens have if we buy eggs from the store though. Oh well, just venting I guess :-( We miss our chickens especially since some of them were the ones we got 4 yrs ago and we were really attached to them individually.
