I read somewhere on here about putting winter squash into your chickens run, with only holes in it so they can keep themselves busy pecking at it. Well, it seems to work really well. I put out 2 since one was too small for everybody to get around. I still think I should put out 3 since the lower on the pecking order are getting pushed away. I figure they will tire at some point, and the others will have a chance. It's quite funny to watch. Here are some pics of my girls.
