Yeah, they were hatched a week ago Monday and they arrived here last Friday. They are really lively! They're also getting used to being handled, as I check them every evening for pasty butt and talk to them. I plan to add grit to the brooder tomorrow and also split them into two groups.I would imagine it loses potency but I also doubt the chicks need it now. Its been a few days right? I used to buy gatorade (red fruit flavored) and mix it in their water.
