I added 4 10 week old RIRs to my flock (of 1 leghorn) and they will go up the ladder to the coop but not down. There is a hole in the floor of the coop and they seem to be having trouble figuring it out after 2 days. The leghorn is much bigger so I don't think size is the problem...she goes up and down all day. Today they went without food and water until I let them out the window. I got them from a farm where they in a run with just a tarp cover and it didnt seem like they had roosts and definitely no ladder. Will they figure it out eventually? I am keeping food and water in the coop but pulled it out today to see if they would come down but no luck.
