I can't believe how strong these Silkie embryos are in the eggs I got from @RubyNala97! We are on day 13 today, and the air cells look amazing, the chicks inside are strong, and things are going so well I keep looking for the other shoe to drop!! I received 16 eggs, broke one the first day (DON'T SAY IT!!) and one had a blood ring. So there are 14 eggs in the incubator right now, and they are all active in there!
Having trouble with temps in the Brinsea Octagon 20 though. I have 4 "accurate" thermometers in there and get 4 different readings. Two of the thermometers are bulb type, they have been calibrated using the ice water test (thanks for that link, BTW, whoever it was that gave it) and they are sometimes a degree different, even in the same spot in the incubator. The other two are digital and there's a full degree and a half difference. Now, I guess to folks who make thermometers, one degree doesn't mean diddly if folks are using them to decide between a long sleeved shirt or a short sleeved one, but it makes a world of difference to a developing embryo over 21 days. <sigh> And I know that incubators - even small ones like this one - have temperature variations within them so when I turn eggs I also switch their locations in the bator at least one time. Because I'm hand turning this group, the Brinsea is opened more than it was with the other two groups of eggs, and RubyNala suggested a slightly higher humidity for these so that makes the temp drop a bit too, I know. I just dread a late hatch with maybe some physical problems with the chicks.
I am absolutely determined that these eggs are going to make it all the way through. Katiebug is counting on Gramma giving her the Silkies!
