it’s no where near enough development for a 23 day old embryo. I dont think it will make it if it were developing all 23 days, but it wont hurt to leave it in
I would leave it in I read a post on here that claimed a clutch of eggs in the incubator hatched 2weeks late after an extensive power outage... sounded crazy to me, but I guess anything can be possible, lol
It looks totally alive and growing but only around day 17-18. I'd lock it down, raise the humidity and stop candling it today though. And shoot - if it's moving it's alive! Good luck.
It does look underdeveloped, i agree. I out them in the incubator the day I got them, Saturday July 10th. I raised the humidity on the 27th, which was the 17th day after they went in. Its been raised ever since. I dont know how they can be so far behind and still alive!
