my chicken broth did not separate with layers
If you didn't roast the bones, then yes, it's going to be pale. Many recipes suggest browning the bones (I like to bake them at 450 for 45 minutes), for extra flavor and a nice color.

As for the lack of fat layer... the bones themselves don't have much fat. If you've got just cleaned bones, then I wouldn't expect a separate fat layer. If you'd included skin, then you'd expect it to have fat.

Either that, or your crock pot is broken, and it just sat there are room temperature for 24 hours.
