so glad you joined us.
Honestly was ROFL when I read your intro, but did a search and there are a number of folks who have also tried this:

I only looked at a couple, but seems the only one who was successful did this when they were already piping.
You should post on the incubating and hatching thread, would love to follow the thread
The only advice I can offer comes from a post in one of the above threads: 1-be very careful during showers and clothing changes! 2-don't post pics - I think that is likely a breach of BYC policy and 3- consider padding to increase the hatching temp.
