Sorry for hatching trouble.

According to your description... humidity is too high. Please tell the temperature and humidity you are using.
Aside from that... your deformities are likely being cause by only one of a few possibilities... Parental genetics, parental nutrition, temperature fluctuations or temp off in general.
I personally will NOT treat splay leg chicks and that is a condition worth culling for me... Once it's fixed and they grow they start breeding and give their now hidden genetic weakness to the offspring.
Human colds do NOT pass to chickens.
How soon are you trying to get them to eat? I have aspirated many a chick trying to help them drink. Some chicks never actually connect with the food, known as failure to thrive. Crushing it extra into mash instead of crumble has worked well to diminish the issue. What heat source are you using after they hatch?
What color are the eggs and from what breed? How old is the stock? Flock age, inbreeding, nutrition and so many other things can heavily impact hatching.
Also what incubator are you using? Do you have all the air plugs out? Are you chicks hatching on day 21? Are you using a calibrated thermometer or hygrometer? Do you know what is fed to the parent flock on a regular basis?
Also, thank you for being brave and euthanizing those that need it! I KNOW what a difficult choice it is.

Adding your general location to your profile can help folks make the best suggestions possible at a glance.


ETA: power outages cause ALL kinds of issues you might not otherwise face! A great resource for hatching information, including reason for failure or POSSIBLE causes of deformities starts on page 52 in the following link...
