How to expand my brooder

[1lilchicken]

I currently have four 2 week old chicks in a plastic tub and I am looking for ideas to expand the brooder. We tried adding a kiddie pool and connecting it to the previous plastic bin but the chicks seem unable to understand the concept of walking through the small cardboard tunnel to cross. The chicks will go into the kiddie pool but not back to the bin where their food and water is. Looking for any advice.

You will have to train them to their food and water.Put them in the water, food side. They will learn their self to go back and forth. In a few days, they will get it right.Make the hole a little wider also if you can. Good set up by the way.
