Is scratch the same as corn for keeping the chickens warmer during winter? I see cracked corn in their layer mix and wonder if I should be giving them extra corn in the evening? The nights are starting to go below 0 Celsius (32 F) Will feeding them scratch interfere with the layer rations? Scratch has oats, corn and wheat too, would that be too much? I feel I should give them some warm oatmeal this week, it's supposed to snow on Tuesday with lake effect squalls. Blizzard-like is more like it. ha Any suggestions for my first winter?
