I tried something else tonight and physically moved two of the game hens into the tree. I didn’t put the Flarry Eye Gray up there because she is the smallest and cost the most money lol. But I figure since one of the Hatch games has already gone straight feral the other two Hatches have a good chance of surviving up a tree. They immediately evacuated the tree and opted for the lean-to but maybe after a few nights of this they will start following the rooster.
