I don't know about your chickens but when it snows mine think it is poison. They sit inside the covered run and look outside. Kinda like me when it is cold. I have been trying to think of something I could do to liven things up a bit. I took 2 heads of cabbage and tied them to a string and hung them from the roof just high enough off the ground so they could reach it. From the time I let go of the cabbage they had them swinging from their pecking. I also fluffed up a bale of straw in the 8x12 run which made it about a foot deep. I then tossed in 3-4 handfuls of scratch and they thought they where in heaven digging and looking for the grain. Anyone else have any ideas to keep them happy and busy? John
