Thank you
It is a least gratifying to see I'm giving these new chickens a better life.
I took the advice about the apple cider vinegar. The chickens in the coop are lapping it up, but the sick hens aren't drinking at all. I've been giving them the medicine with an eye dropper, but do you think I should be giving them more water that way too? One is improving more quickly then the other, but it doesn't appear either of them is eating or drinking very much.
Interestingly, I'm very allergic to all antibiotics that end in -mycin. So I've been handling it with care. I wear gloves when I'm mixing the medicine or treating them. So eating the eggs is definitely out of the question until well after the medicine is no longer being administered. The vet seemed to think the eggs would be fine to consume once the birds are 100% recovered, and the medicine is out of their system.
I know the farmer I got the hens from gave away lots (like dozens) of other chickens to other folks. I tried contacting her to tell her my chickens had fallen ill, but she hasn't responded.
