I have two 6 week old pullets, and I am curious what to expect. I will only have two hens, if we do get anymore we'll adjust accordingly lol, but I don't want the feed to go bad. How long would it take two standard breed (Barred Rock, and Easter Egger) hens to go through a 50 lb bag of feed? (including waste sadly.. unless you have non waste tips in that case chime in) Should I buy smaller quanities? Will feed go bad before they go through it? I know most have larger flocks, but any input is good input. I hate to keep paying by the lb if the feed doesn't go bad quickly. Thanks again. (will probably store in metal garbage cans with bungee shut lids).
