i'm at a loss i had an unopened bag of goat feed and chciken feed in the shed and when i opened them there was little brownish reddish bugs in them. I've never seen then before. what are they? and will they hurt the goats if they got them? i didn't see them till after i put the feed in the bowel and by then the goats were already chowing down. What do you store your feed in? I didnt think bugs could get into unopened bags. I'm looking at 58 gallon plastic drums would they stay out of that?
