Managed to claw my way through revising several more riddles. I did 13 through 18. Changes made throughout.
In #13 “Ten Chickens” I decided to go with Bernard Muir’s revision of “side þy sarra” for ASPR’s “siþe ne sarra,” which changes the meaning quite a bit. So I used “their sides not more tender” rather than what I had before, which always seemed like a stretch to me anyways.
