For the 3rd time in a month, I'm finding sticks & stones in my feeders. Not in the coop, nor in the outdoor feeder, but just INSIDE!!! I have found sticks as long as seven inches, & stones from marble size to larger then a golf ball, IN THE FEEDER!! Now, I live alone, (except for my chicks & cat) so I know no two legged varmint is messing w/me or the chicks. If I close them in @ night, or leave outside access open, I still occasionally find stones in the feeder! I fill a five gallon water bottle w/the feed, then invert it over the bowl, & this is hung from the ceiling w/a gap of about 1/2 inch. I also "funnel" my feed into these five gallon bottles personally, so I know there is no debris in the feed sacks when loading the feeders. The funnel size would not permit passage of stones above 1/4 inch if @ all. My coop & run has been called "chicken alcatraz"-no one in-no one out!! No chick I own is able to carry stones this size, or quantity!! My entire run is 1/2 inch X one inch welded wire. All vents are same sized wire covered. The coop is absolutely rodent proof!! Can anyone tell me where, how, or what I may be missing here??
