Low temp in incubator days 1-3

[tsid78]

Hi Everyone,
I need help! This is my fourth chicken hatch but my thermometer flopped on me during the first three days of incubation. I noticed towards the end of day 3 that my temp was about 93 instead of 99. I’ve read that this can cause abnormalities and malformations. I’m a classroom teacher so trying to avoid any possible culling. I candled them today on day 4 and two are already showing veins. If I have to get rid of them I would rather do it sooner than later!! The temperature has now been adjusted but any help would be so appreciated!!

I wouldn't worry. Get the temps right and don't candle for another week. Turning is extremely important at this point.
Temperature variations aren't a death knell unless they go over 104.
