Need opinoins please... Just discovered that my theory of always having feed on hand has backfired. I keep two bags of feed at all times - and rotate - so the first bag gets used, I go buy two more bags, the second bag gets used before the two new ones.....well, my farmhand-helper son (age 13) hasn't switched the bags.... So we have a bag of feed from February 2011. It's Purina Flock pellets (sorry, forgot the 'real' name). Would you use it? Should I ditch it? Thanks for the opinoins. Don't want any chickens sick, but it seems fine (no mold smell, just regular ol' feed smell). It's been stored in a dry place (hayloft of barn).
