HI, My chickens refuse to go up into the henhouse to sleep on their roosts in the night. We have to carry them up, and then they happily huddle up all together ON THE FLOOR. They're supposed to sleep on the sticks right? They are only a few months old but still. But even that's not the main problem. They won't go up the ramp. Only one of them will go up but only if we put about four pounds of treats on the ramp and in the henhouse. Why are my chickens so stubborn!?! Please tell me how to get them to at least go up their ramp and maybe how to get them to roost on their sticks too. Please help!
