Hi to all. First post but have been enjoying this site for a while and it has helped tremendously as I built my coop and purchased my chickens. I have a little extra money right now and wanted to buy a bunch of layer feed in 50 # bags and store it. Could anyone tell me how long it should last without losing nutritional value if it is kept dry? I would think it would last a very long time but want to get some experienced opinions. Thanks much to all who respond. This chicken raising is much more fun than I would have thought !!!
