Long story short yesterday after noticing an odd smell from one chick i discovered seeds in the bedding. I promptly removed all of the hay and chick starter from the box. gave them vinegar in there water and fasted them all night. this morning all of their crops were empty and the smelly beak didnt have any odor. I fed them this morning and again at noon but when I checked on them just a moment ago I noticed a light smell on mister smelly beak. Any suggestions?
