I have a long ramp with 1" half round every 8 inches or so. Too big for chicks, but DH was not up to making chick AND chicken ramps (can't blame him). Anyway, chicks wanted no part of it when I moved them in at 5 weeks. We spent the first 2 nights cornering and catching them - not fun.
Their favorite treat is cooked egg yolk, so I put some on a paper plate and kind of moved it up the ramp in the evening.
It took about 3 tries, but now they go right on up (even with an empty paper plate!) It's been less than a week since the big move, and no more chasing.
I take great comfort in reading on this website that they all figure it out eventually, like when people told you that no one goes off to college in diapers although you were worried when your kids were 2 or 3 and thought wetting the bed was fun.
It'll work out - good luck!
