i am not sure what its called but the things you can buy for your car to reflect the sun, they are silver with a bit of some type of padding in them??? i used one to reflect the sun from the storm door this past summer and i know they started picking on that and made a couple holes so i took it back down. they wont eat anything though, i made some biscuits that they refused to eat.defiantly not Betty Crocker.
Have you tried shucked sunflower seeds or sprouts? My chickens go gaga over those things.
Not like biscuits?? Thats pretty crazy chickens usually love bread.
