My chickens are in a tractor but have been free-range most of the day since spring. They seem so happy to be out, but we added 2 new pullets a few weeks ago, and things have gotten much more complicated. It used to be that if I wasn't going to be around right at dusk to lock them in I could just call them and toss a treat into the tractor, they'd go in, and I'd lock it. The 2 new ones don't know to come when I call, and I can't always catch them, so I end up being out there at dusk waiting for them to go in so I can lock up when I really need to be inside putting my kids to bed! The pullets wait until the hens are in and then go in maybe 10 minutes later. I'm trying to give lots of treats so they learn what it means when I call, but it doesn't seem to help. I think they are reluctant to come near me when the hens are around for fear of getting pecked. I think that's why they go in so late, too. I sure hope things improve once they get the pecking order sorted out!
