Same here Vicker. In the late afternoon in winter I mix their regular food with some 5 way scratch and toss it around the barnyard for them to peck/eat. I don't think they get to much scratch that way as they go through more than enough of their lay feed during the day. And at night, when the temps get below freezing they seem to huddle up to keep warm if they feel cold.Scratch can help put on fat, which can help insulate them. I give food scraps and fat trimmings or suet at times. I primarily use scratch to scatter around the run in winter to give them something to busy themselves with, since bugs and greenery are minimal at that time. My birds have a large run, so I don't measure out an exact amount per bird to give every day. I can see that they aren't pigging out on the extras to the neglect of their regular feed.
