After my guineas hatched i gave them organic chick feed, and they were eating it. the bag was about three months old. but after a week or two they stopped! and they refuse to eat anything at all not oatmeal not buckwheat. they would eat nothing but worms. but now they are a month old and they are so thin and starving and they still wonlt eat anything but worms. what do i do? two of them already died of starvation!
