First off I have to give them credit for making it full term...they survived over a 24 hour power outage, below average temperatures, my newbie mistakes and out of 15, 8 made it to day 21...none hatched or begun until day 24 and only one made it to the external pip stage then died in the shell. Most of them were facing the opposite direction of the air cell which is wierd because they were propped up with the air cell end facing slightly upwards, should it have been more? Humidity issues maybe?
