gonna try that, even though I have been getting a a fair amount of eggs all winter, what I've done is add an hour or two of light, plus extra food/protein - the treat they really like is the "Nutro Nuggets, Lamb and Rice" dog food from Costco - it runs about $23 for a 40-lb bag and I toss them about 2 - 4 cup scoops in the afternoon (for about 65 hens) - so the bag lasets about a month, they also get all kinds of scraps, meat, bread, veggies, whatever we can find. We had a cold spell in early Dec and up til then I was getting about 30-33 a day, when I added light, (and heatlamps on the really cold nights) it jumped to 45. Check your local backery outlets for dayold breads - one of ours sells a grocery cart full for $7 - I give them about 3 loaves (for 65 hens) as a morning treat and on really cold mornings I sometimes make them oatmeal (with oil added to help raise the omega 3 (along with some flaxseed in their feeder)
