every morning when I let the ladies out to free range for the day and I throw scratch down they act as if they have not seen food for days (same thing at night when they go into their coop area and see their feed) but they have access all day and night to their feed and water. (Extra water during the day but they seem to like the fish barrel instead). Should I be feeding more feed and scratch? They love to free range and I see them neatly trimmng the lawn. (1 area my husband no longer has to mow they keep it so trimmed). Or is this normal? They appear to growing and happy.
