You should be able to get regular commercial poultry feed at 20 or 22%As to upping the protein and fat levels. Yes i been thinking i do need to do so. Any recommedations on how to do so ? The last bag of feed i got from town did
When temps stay below zero F for extended periods I find adding more fat and protein is helpful. Freezer burnt salmon, and left over fats from cooking that I then mix up into their feed works well.
I have never been into feeding wet mash... by the time you get it walked out to the coop, it will just be a cold to frozen ice block. Fat mixed into the feed doesn't freeze as solid/hard as water.
My older sis adds cat food in the winter.
If you don't want to increase fat or protein, you could probably get by with just keeping their daylight at 12 to 10 hours. Chickens will not eat in the dark.
