One of my 4-day old Welsummer chicks refuses to eat her chick starter. She only pecks at it a few times before losing interest, even though I tap and show her where it is. I nearly lost her yesterday, as she was very weak. I nursed her back to a semi-decent state with sugar/vitamin water and baby crickets. Now she is crazy about crickets but still won't touch her starter. I am going to try hard-boiled egg yolk. Any other suggestions would be appreciated.
