I am new to chickens. My chicks are 4 weeks old and I now have them out in the coop during the day. When they were very young they would eat the starter food like crazy, I was filling it twice a day. Now that they are older they rarely finish a single filling per day. Is this normal as they are pecking and exploring the coop more or should I be feeding them something else other then starter feed? I have tried throwing in small vegy pieces and oatmeal into their feed at times for variety but they don't seem to be crazy about that either.
