Jakes often tend to be scrawny this time of year. Finding Jakes that are scrawny only means that they have been strutting a lot. Allready starting out on the small side, then strutting, which includes not a lot of time for eating, burns up the little fat supply they may have. Another thing you may find, if you are seeing scrawny jakes is, either no big tom around, thus allowing the jakes to feel comfortable enough to strut without gettin the crap beat out of them from the tom. Or an over abundance of hens, and not enough big toms to keep track of all of them. Either way, best to move on to another area, or consider taking the jake and headin home and having a beer.
