I am new to raising chickens. I have 5 polish hens that are about 7 weeks old that have just moved into the outdoor coop. The coop is connected to a run and the chickens have no problem going down the ramp into the run, but they don't seem to have figured out how to go up the ramp into the coop. I was wondering what to do when it rains, like it is now. I have read that polish hens don't like rain because of the feathers and because they won't go up the ramp, I'm not sure if I should let them out of the coop. They can go under the coop, where it is mostly dry, but if it rains all day, they'll still get wet. The ramp is a bit steep and is 7 1/2 inches across. Should I make the ramp wider?
