Need some advice here.
Still just the one baby that was hatched on Monday.  One egg cracked open yesterday, but it was obiviously a quitter as all I found was a mass of really stinky matter.
So, today, I decided to float test the other 4 under her.  They all tested viable - only a small portion (maybe 1/6 - 1/5 of the egg) above the water line.  According to a post I read on this site this means the eggs are viable and at maturity.  I thought I saw one moving in the water.
Momma got off the nest and brought the one baby out into the coop, presumably to teach it to eat and drink.  I do have water and food in the coop for them.
She returned to the eggs and is sitting on them again.  If I count the first 24 hours as day 1, then today is day 25 for these eggs.  They didn't smell foul when I float tested them.
I am inclined to wait until momma completely abandons the eggs before taking any action.  Does this sound reasonable?
Edit:  right now, momma doesn't have a way to take baby out of the coop, as the step up is too big for the baby to navigate.  We will be changing this today when all the hens are done laying.
Thank you.
