is this frost bit?

[Louis3]

I just noticed thus the other day. The hen is eating fine and i see no other symptoms of anything. 2 of my other hens have this a little bit (1 or 2) spots but my 2 RR do not have anything. Thanks for the help!

To me, it looks like frost bite

Thanks for the response I wasn't sure I would have thought that the tips would have frost bite before the main part.
