I moved 2 chickens into a chicken tractor a while ago, and I just realized (finally) that they're not eating the layer pellets in the feed slot which is accessible from the ledge. I knew they weren't bothering with the nest box, but they're still fairly young, <1yr old. I guess they've been subsisting on foraging. So, I've sprinkled chicken scratch on the ledge where they can see it, but they won't hop up. All my other chickens do this with zero hesitation. The ledge is maybe 11-12" high. They're supposed to hop to the roosting post from there, but of course, they're not doing that either. Now I'm feeding them on the ground so they won't starve/dehydrate. Will they just one day try it?
