My run is located right next to the vegetable garden. I want to let the chickens out to 'free range' the vegetable garden. It is fenced but only a four foot fence. There is lots of good pickings for them in the garden. They have never been out of the run and coop. Oh, and they are 20-21 weeks old. My understanding is that if I let them out maybe an hour before dusk they will naturally head back to the run and coop at dusk to roost as usual.....not wanting to risk my chickens I will be sitting out there with them, favorite treat at the ready, making sure all make it back in. Will this work? I hate to waste what is left in the garden....plants and bugs...when they would enjoy it. Plus, there is the added benefit of the fertilizer. Maybe I should just let a few out the first time? Need advice here. Thanks!
