I get a all star pellet in my local feed store which cost me 17.50$ per 50lb. I have 4 silkies and 2 leghorns 1 roo and 1 hen and also 4 ducks. The 50lb last around 4 weeks or so. So thats around 2lb per day for them. Is that enough? I also let them free range so they can catch what ever there is on the grass/dirt.
