Hi all! I have a batch of 25-or-so RIR/Rock/Sussex/Orp chicks that are about 2 months old now, and I'm wondering if there is anything I can feed them in addition to their usual feed that will make them even tastier than they already will be? They're currently getting Flock Raiser, plants from around my yard, and some extra stuff from the pantry. Need lots of fat for potato frying... Thanks!
