Alright this is WAY out of the box, but WTH. If you get a mother mare with an engorged udder, so taut the foal can't drink, you use suction to ease that situation. You get a glass bottle, like a juice bottle or wine bottle, warm it up by pouring boiling water in it, dump out boiling water, make sure rim is not too hot, hold it firmly around the teat, rub ice cubes around the base to create suction, and BAM, out pours mum's milk. Might that work for an intractable egg? A little suction?
