The grocery delivered the wrong peanuts - I ordered raw peanuts for making peanut brittle for the holidays (Yum!) but I got a huge bag of shelled peanuts, unsalted, for wildbirds, etc. Are they safe for my chickens? I have five Black Copper Marans and they are good eaters, very fond of almost anything I give them. I don't want to give anything that makes them sick. Thanks for any info y'all may have.
