That is awesome! That should work fine. In a matter of fact I bought a new brooder/kennel for my new chicks because of the limited space in the dog kennel.
I have bsl and rsl I attached a picture of them 3 days old. My BSL were completely black no white on them. My RSL were harder to tell- you can see by the first picture the whiter chick was a Rooster.
As babies they need to have there temp at 90 degrees and move at about 5 degrees each week...
