I need help understanding how to manage free-range chickens....................I know they need to be locked up at night and let out in the morning. 1) Q: If you use feed to get them back in the run, does that mean they forage all day on their own, receiving food at lockup time only? 2) Q: If I use a tractor coop, do you need to have a fenced run around that? 3) Q: If you put feeders / feed on the ground, what keeps ants and bugs from getting into the feed; so, should the feeders be hung in some way instead? 4) Q: If I only have the tractor coop with no fenced run, and am trying to round them up at night, do you put food in the coop? And if so, isn't that an invitation for poop to fall from the roosts into the feed resulting in sick birds? My apologies for the weird questions. Still trying to "know what I'm doing" before I get into full-time chicken work!!
