I personally snatch them out once they are up and walking around pretty good. You don't have to worry about water and food for a couple of days, but, I find that they do like water after around 24 hrs. You can put the food near them too..some will try and peck at it. I will throw some on the liner I have over the wood chips for a while. They see it, peck at it.
4 babies? Woot!
