I am feeding medicated chick starter, 25 lb. bag stored in galvanized trash can with lid, about half used and this morning I noticed a lot of small, rust-colored exo-skeletal (beetle-like) bugs in it. They are about 2 cm long and narrow with six legs and antennae. Does anyone know what they are and if they are bad - should I throw out this bag, or is it just another source of protein for the chicks (10 wks. old)? Any info. welcome. Thanks.
