My birds have allergies, buy some are getting really bad. Only issue is some have newly hatched chicks at their side. Is it still safe to treat them as if they have URI? Also I went to remove the empty egg out from under the hen and there were a ton of ants. So I picked up the eggs and the chick, then her, and placed them up off the ground. Is it safe to use 7 dust even with the newly hatched babies? Thank you all!
