"Dog crate" Brooder - 2 levels?

[Ytuni]

I have an animal crate that has an upper level accessible via a ramp. Would this acceptable to use for brooding chicks? Should I keep them on the bottom level then add in the ramp once they're bigger? Or is there to much potential for them to get injured falling?

Could you post a photo(s) of the animal crate?

And give some dimensions too, please?
