What else can i give them to get them some 'extra weight on their bones' to keep them going throught the cold winter nights? I have tried two different kinds of scratch. i have found the ultimate scratch at our ag center, and they look at it like 'whatever' and walk away. They are starting to look a litte ragged and skinny! Have any of you had feathers that started to look freyed? almost like the little tines of the feather are breaking off? Like split ends on our hair? why? i am wondering if it is a deficiency or if my roo is being to much of a 'happy camper' ?????
