Grew up on a farm in Scandinavia and have witness a few of these up close. The amount of debris they can accumulate is staggering - mostly nails, and corroded clumps of metal (probably from old farming equipment). There was nothing particular about the fields where their food came from, in fact it would be considered very clean, almost ecological. But hundreds of years of harvesting will leave a footprint. Also, in the earlier days when renovation was not set in system they used to bury their trash (what else could they do really).

My father always explained that interest for rusty metall with the cows attempt to balance out a iron-deficiency. Could be wrong though.

Found there behaviour always fascinating. They internal groom-group friendships and the one or two weakest cows they would trash up to feed them too any predator(yes, they have a social life in that way).

Not happy how dairy farming selective breeding has crippled them. If you have to inject a hormon into a creature for milking, else it gets sick, you have overstreched it to the point of crippeling.

still like farmers though and without them cows would go the way of everything wild in that juicebox that is earth.
