Help please! This is my first time with my hens hatching chicks, we are on day 22, I have one egg with a crack.. (A Zip) . A couple that have small spots that look like they are thinner..I haven't touched all of them because, well I have 2 momma's that don't like that idea.. I live in Indiana, IT IS COLD! I have a "sweeter heater" ready for the chicks if they need it , and a red light in the coop too. What do I do after they hatch? Do I do anything? Will my momma's take care of all of it? ( keeping them warm is my concern really) Any help is greatly appreciated, I'm super excited, I've had my babies since they were 2 days old, I've raised chicks before, but I don't want to separate them if I can avoid it. I have Silkie's, 3 hens and 1 handsome rooster, ( my rooster even takes his turn sometimes sitting on the eggs) . Thanks guys!
