Have a brooder ready already at temperature. They can hang out in the incubator for a while until they are dry and moving around.
I have put all my chicks, hatched and bought on Tucker milling chick starter. I’ve had 50 or more chicks at several different times and haven’t lost one yet. Have water and food ready.
Hopefully you have a decent sized brooder with a warm side and a (not as warm side) so the chicks have room to find their perfect temperature.
There are electrolyte packs you can get for chicks. I wouldn’t say it’s necessary but everything helps. Mix it Up with some water and give that to them.
What is your brooder setup?
I have used medicated and non medicated chick starter. It’s up to you to decide what your comfortable with and what the chickens will be raised for.
