Yup, the only time I have seen bald faces in younglings before the feathers break skin surface was in some ducklings that got at sticky mud matted into their down and didn't get it washed off before it dried... once it dried it got itchy and they scratched it off, tearing some fluff off in the process... for that much baldness and on chicks, they were in awful conditions for extended periods... not to mention the ground in dirt the OP even said is still there...
