I have baby chicks that I am moving to the outside coop (with a heat lamp at night until the weather warms up). They have a ramp that goes from the floor of the coop to the ground underneath (the run). Not sure how to teach them to go up and down. I put them in the bottom part yesterday and they didn't figure it out. Then I put them in the top part last night and one got down the ramp, but couldn't figure out how to get back up.....UUUGGG!!! Any ideas???
