Penguin has a sibling! She hatched another one. Once again, I was hearing a baby bird screaming when I went in the garage. I made the executive decision to just take this one and put it in with penguin and let them be company for each other. Her eggs are cold again. Maybe she'll get back to them before it's too late and hatch another in a day or two... The little thing was pretty chilled, and is now warming up. Like penguin, it already thinks my hand is a good thing. That means another round of teaching how to eat and drink (yikes). Maybe it will learn from penguin.
