Hmm, I couldn't say for sure by the photos. How sad they came like that,...if I understand correctly.
Are they exhibiting other symptoms, or limping, seem to be in pain?
We treated one, also had another we did not treat...both situations healed. The surgery was done by us, not a vet.
Also, we have used some penicillin purchased at a farm store for animals and adjusted for the birds size. I don't know if this is best, but have used this product several times on various illnesses in our birds with some success. Infection, is an issue...of course.
Another earlier post stated a product they used...could work!?...
We used a triple antibiotic ointment on ours, and again..success
The triple antibiotic came out of our people supply of meds, so I had to replace our families triple antibiotic!...
Not sure others believe in doing any of this on your own, but I get resistance from the family in taking them to the vets....So, we try our best and truly love the hens! Well, roosters too!...and ducks, lambs, goats,....
Keep us posted on how the feet situation works out!
