There was an issue with our electric company the first part of the month, and there were dips and power surges like crazy. Ended up losing all the eggs in their last week of development, save two...a little Silkie who hatched a day late, and two days after that, an Ameraucana who managed to zip about an inch before the membrane dried it's foot fast to it's head so much the poor baby could only wiggle one toe. I got the top of the egg off and dampened everything down enough that the chick managed to get out of the rest of the shell on it's own so that all yolk was absorbed. I was gutted about the 2-1/2+ dozen eggs with dead, mostly developed, chicks inside. But the two chicks that made it, both are doing just fine and are growing like weeds, and for that I'm very thankful.
