I called the TN. Department of Agriculture and talked with the outreach coordinator. The requirements for resale if you have less than 3000 birds are:
No license required.
Unused egg cartons that have your name, address, and the word unclassified on them
The eggs must be washed and sanitized. For sanitizing you can use a solution of 1 T. bleach / gal. water (YUK!) or a vinegar solution (better).
and that's it.
There is also a poultry processing exemption if you process less than 20,000 birds/yr., but I didn't get all the particulars about that.
They were very friendly and helpful!
Fun fact-
In Europe it is illegal to wash and egg for resale. They feel it promotes uncleanliness if you wash them. They may be smarter that us. There is a new study out (from Sweden) that kids have more allergies if their food has been sanitized/sterilized/disinfected.
Thanks for calling and clarifying. Always better to get info "straight from the horse's mouth"!
