Which antibiotics call for permanent egg withdrawal? Most of the antibiotics I've used/seen/heard of recommend egg withdrawal for a 3-4 weeks and the exact timing depends on the specific medication.Did you wear gloves when you handled her out there? If not, and you don't have that raccoon, talk to your doctor and/ or public health TOMORROW about your exposure to this raccoon's saliva, as they are major rabies carriers. Just do it!
About your hen if she's eating and drinking, that's a very good sign. Could you get her to an avian veterinarian? Otherwise, warm water to rinse these wounds, and an antibiotic wound dressing, Neosporin, better yet Silvadene, at least. Maluka honey is good too as a wound dressing. Pain meds!
Black tissue is dead tissue. Nothing like that yet, anyway.
Oral or injectable antibiotics, maybe, although then no eggs from her can be eaten, if she can lay eggs again.
All the best for her recovery.
