Please, show me pictures of your feeders and waterers that can be filled from outside the coop/run. I'm involving my 7yo in the care of the chickens because he's enthusiastic about it and because he's old enough for a degree of supervised responsibility. But I don't want him opening doors and having the chickens get out. And besides that, there will be times that I'll need to be feeding/watering chickens when already in my work clothes. So I want outside-fill feeders and waterers to replace the handing feeder and the double-walled, metal waterer up on blocks. I'm particularly interested in seeing nipple drinker systems and feeders made of PVC pipe, please.
