@Ky hills ... just a question... how many chickens do you have ? I have had 125 down to 5 at different times... I have a smallish bulk bin (1 ton or so) that I put up and get a bulk delivery of poultry feed when they bring the cattle feed. I have had it in the bin for a year now as I am way down in chicken numbers. Someone said that the feed could get moths or worms in it and I said so what... chickens like worms/larvae.... it may not be perfect but it sure beat the extreme cost of bagged feed. AND is keep the rodents out of it....Since you get bulk feed delivery of cattle feed, you might want to check into it....
I usually get it filled in the fall so it goes 4-6 months of cold when there isn't the problems with meal worms or anything like that to start with. As long as it doesn't have any leaks and gets moldy, they do pretty good. My birds do get out loose for some free ranging when I am around due to hawks...
