Out of all the available ones in my collection the only underpants that visiting moths picked out to chew into last year were organic (three different ones in two different colours). So if you would like to avoid toxic and unfair cotton too, let me direct you to People Tree and Hessnatur (you’ll need to understand German for that one, but well worth the effort), but do make sure there are a lot of smelly things around to keep moths at bay, cedar wood, lemon, lavender, lemongrass, citronella, etc.
We had four home-born cockerels who were tolerating each other until M gave us a beautiful new one who had been born out of a blue egg, so we sacrificed and froze two cockerels for later consumption, put another one in a temporary enclosure and kept our favourite one to share the turf with the new one. They had a different idea, within a few minutes there was blood pouring from the combs, twisted toes from wild jumping and awkward falling, so we grabbed each of them and gave each a short cold bath in a bucket. They went back to fight after a while when they felt their dignity had dripped dry so they got another short snappy dip (very easy to catch a fighting cockerel), and then they got smart. On day two they are minding their own business.
Any blood (from fighting cockerels, home births and what have yous) stains should be immersed in cold water for a few hours (add salt for maximum effect or for stains that have been allowed to dry) before being thrown into a cold wash. The idea is to have cheap salt in the house, keep unrefined sea salt for the table and white dug-out supermarket stuff for emergencies (sprinkled heavily on red wine stains works well too) to see how the stuff is dug out from under the ground, watch Our Daily Bread directed by Nikolaus Geyrhalter (and to see, with dropped jaws, what industrial food production looks like, highly recommended).
