I have never done this. In theory this should work as a regular shell. I'm not sure about the coconut oil, if that's what you're meaning.
I believe @WVduckchick meant that for you to moisten the membrane covering the chick so that membrane doesn't dry down and shrink wrap the chick. At the time you took the pic above, the membrane appears to look good.
Yep, read back to post #8. She moistened both. Sounds like it made a nice replacement shell. I'm just not sure if the chick will be able to break thru a double layer in the areas that are doubled.
