One of five 8wo chicks I keep in a small enclosure, dropped the feeder which was hanged with the ribbon and most probably swallowed it. The chicks are all different breeds, but I saw many times a silkie trying to peck at the ribbon. Two days ago I found the feeder on the ground and no sign of the ribbon around -I searched thoroughly. All chicks show no abnormal behaviour yet, and drink and eat normally. Is there something I could do -add something to their feed perhaps to help it get out- except for waiting to see if one comes down with a problem?
