I'm looking at various chicken tractor designs. The A-frame styles look likely because I'm wanting to build something simple that doesn't look too obviously like a chicken coop for 4-6 stealth bantams. I get how you build the nest box into the end and have an egg door there, but now for the possibly stupid question, ... How do you get the feeder and waterer in and out? I don't see openings for them in the A-frame designs. And can it be arranged so that feeding and watering is done from the outside without risk of chicken escape? I'm wanting to involve my kids, especially the 7yo, in the chicken care and it would be a lot easier for him to not have to open anything large enough to let a chicken out.
