We have three Giant Blue Cochin pullets that will go down the ramp from their coop but not up! They wait happily for my husband to pick them up (all three at once) and put them back in each evening. They will roost on the "practice roosts" that are two inches off the coop floor, but not on the roost that is less than two feet up. These girls are now almost 5 months old and live in their own coop and run. We are thinking of having two of our easy-going Ameraucana pullets (6 months old) room with them for a while to show them the ropes. We also plan to add more treads to the ramp and run a trail of feed up it. Is it normal for cochins not to use the roost? Is it because they are so docile? Are they usually timid about trying new things?
