Hello everyone. I've noticed lately that a couple of my three week old leghorns are often times laying in their pine litter and kicking it away as if they're digging "a nest" and then either once they're very deep down to the point of near buriel, or they start rolling around in it. I am assuming this is the dust bath behavior since I am a newbie and unsure. My question is, should I put a little box of sand in the brooder with them or something? Or just let them continue digging holes in their litter, and if I did put a box of sand in with them, is it safe for them? Any help would be great, thanks!
