Ok thank you for assuring me its somewhat normal in buying poultry. Im new to this and was upset about the loss of some and potentially more.So very sorry to hear! I understand too about the sad and angry part... it is so hard, especially when kids are involved. Please don't fault the seller too much - mites is something we all deal with...the key is to prevent, or to catch and treat before they really become a problem. Wild birds will bring these things in so getting them in the first place can happen no matter what you do. ((well, there is always house chickens))
I don't know how common the issues are with mites - cant really speak to that - but in general, parasites will weaken a bird. Then they were stressed from the move - and they are young to begin with, which make them more susceptible. I hear that kittens and puppies can quickly die from just flea infestations.
I would go with the sevin, even if it just this one time - a quick kill of the mites may be best chance your chick has for survival.
Anyone have suggestions for icu treatment for the remaining chick? sugar water, elecrolytes, etc? Don't know where the bird is, but maybe brining it in so it doesn't have to deal with temps, in rubber maid tub so you KNOW there are no more nasties nearby waiting to jump on again.... I might even through the idea out there about bathing to make sure the mites are off, but that is a lot of stress to the chick - well, not the bath - but the drying and potential chill afterwards. Other folks - PLEASE CHIME IN! These are ideas - but I have no real experience with this.
I just did the seven dust. My husband was not happy about using it but I want these babies to live. Im trying to give the newest sick one molasses water. Hoping she will perk back up. How long do I need to wait before letting my kids touch the birds again?
