I just checked the label of our pellets. It doesn't mention hormones (only enzymes, which is not the same, not sure what they are supposed to do in poultry food), shouldn't any additives be on the label? Or does "based on soy beans" count as a phytohormone?
I'll definitely reduce the pellets again now, although we saw a huge change in lay with our ducks after we introduced them (from 1 a week to 1 a day).
