I will be taking my 50 laying hens through the winter, and with the cost of feed so high, particularly organic feed, I am eager to save any way I can. The mill where we get our feed has an organic pre-mix-a 60# bag will make 2000 lbs of feed. They said to mix with "ground grain" I have an organic farmer lined up who is out of corn, but can sell me organic oats or wheat at a really good price-but he wants me to purchase a fairly large quantity to make it worth his while of course. So, what I need to know is: How many pounds of feed would 50 layers gor through in a winter? (this is Iowa, so winter is essentially beginning of November-end of April) Is a nutritionally balanced pre-mix, mixed with oats and/or wheat REALLY going to be ok for them? I am somewhat skeptical about there being no corn in their diet. Does the wheat/oats need to be ground before feeding, and if so, how fine? Thanks so much for any and all help anyone can provide!
