I recently noticed my girls digging through the horse droppings in the pasture. They only go for the 'fresh' ones. They must be looking for the tiny flies these piles seem to produce. How bad can that be?
LOL....thats why we first got chickens. I was tired of scooping the paddock. Let those little things loose and I never had a pony-pie last more than an hour after that.
No biggie at all! Chickens have been doing that since people started keeping them. My grandpa used to throw cracked corn on piles of cowpies in the pasture to encourage the chickens to spread the manure on the field. Chicken's are gross that way- like a pig they will eat just about anything!
