I have 6 chicks, about 2 weeks and change old, and growing so fast! They graduated from a brooder storage tote to an extra large wire dog crate as they were a bit cramped in the tote. One has started to do a dust bath in the pine shavings and boy is it cute. Question is: should I be giving them some sand in a dish to be a real dust bath for them? I'm in Wisconsin so it will be a bit before they are outside at all, and even so the ground is so wet yet. Hoping weather will cooperate in the coming 2 weeks for some trips out to start introducing them but in the mean time, do I give them something in the crate?
