We have had > 18 inches of snow on ground for a week now. Songbirds now getting hit hard. While driving home from work I saw multiple smaller birds on road flying very weakly. I doubt they will survive night. When I checked on chickens in pens, they jumped down from roost looking for food even though almost dark which is a sign of major hunger. Upon looking at snow around pens, a very large amount of small bird feces was evident and it was reddish because they are consuming the calf manna used as part of my chicken feed mix. The songbirds are eating a very large portion of my chickens feed. I have seen anything like this since after blizzard of 1978-79.
