... I put mama hen and baby back in the coop but now I'm a little nervous... because mom is going crazy kicking up all new bedding and inevitably making DE dust go everywhere... I'm nervous about the mites returning...
First of all: Every hen with chicks goes crazy kicking up a cloud of dust, DE, dirt, grass, wood shavings, leaves, straw, and any other thing that she can kick up, so there is nothing wrong with your hen.
Just a note - I tackled red coop mite and found them happily living in a thick bed of DE... in my nestboxes...
Second of all: Face the facts, the mites can not be said to return because the DE (Diatomaceous Earth) has not sent your chicken parasites to mite heaven. You certainly still have the same old population of mites on hand, all able and willing to take right up where they left off.
And my situation seems similar to yours, in that the threat of a mite / lice / worm etc. etc. issue will never be completely eradicated because I have around 20 wild chickens that hang out with mine as well as other wild birds, peacocks etc., cockroaches, snails that come and go as they please. So it seems mostly about monitoring that things don't get out of balance, I'm gathering. Best of luck to you and yours and me and mine!
