I know that goats don't actually eat everything as a general rule, but I was thinking if he took a bite like they normally do, it's possible he found something in the feathers that he might be missing in his diet. People and animals eat weird things when their dietary needs are lacking for some reason. He may not be absorbing enough keratin or need higher protein. Or he may just be an odd duck... errr... goat.... errrr duck goat.
