I have 6 chicks in the brooder in the basement. It's a GQF metal brooder and has a bottom tray to catch the poop. The tray needs cleaning, of course. There is always a pile of crumbles on the corner near where the chick feed is. I feed medicated crumbles. It's not a lot, probably under a cup. If I just dump it out in the yard, will it hurt my older chickens when they are out free ranging? Because I know they will eat it! LOL Or should I take it out where the chickens don't go to dump?
