About 6 months ago I got two bags of "organic type feed. - it mostly made from cracked natural grains and added supplements like oyster shell. So it is not typical stuff from Feed store. The problem was chickens liked it but not very much. So I ended up with mixing it with regular pellets bought in the store. So i ended up with one bag sitting for 6 months. I just opened it - it looks okey, but I am in doubt if I should feed it. Any advice?
