Sick feral pigeons

Question
Hi there.

I know you're an expert in breeding pigeons, but I'm hoping you could answer a couple health questions about some feral pigeons I've been trying to rehabilitate for the past little while.

The first bird is a female who has been with me for about the past six months and has always shown PMV-like symptoms - upside-down head turning, disorientation, difficulty flying, et cetera. She's been medicated with a variety of things from Avivet (amoxicillin medicine) to pure amoxicillin powder to Triple-Sulfa, supplementary vitamins, and she always has ACV in her water for her health. None of this has helped her at all. Is there something else I could try with her?

The second is a male (I think) who has been with me for only about two months now. He was found freezing to death outside and taken in initially just to warm up and release, but when I noticed his poops were constantly extremely watery, I felt something had to be wrong with him. He has a hard time keeping weight on him (his breast bone is always quite prominent), too. He's been medicated with Avivet, spartrix, ronidazole, and Triple-Sulfa, and has gotten the same supplements as the female. He has grown considerably in strength and seems to think he's quite ready to go, but his poops are still extremely watery and he still can't seem to keep any weight on him. I think I'm out of ideas here, too.

Any help you can offer would be appreciated! Thanks a lot.

Answer
Certainly not in my realm of expertise.  However, it has been my experience that similar symptoms always turn out to be coccidiosis. Do a bit of research on this parasite.  A stool sample to an Ag vet should find out if this is the issue.

2nd thought that comes to mind is Dr. Hollander's work with genetic diseases; primarily using them to map chromosomes.  I wasn't interested in this aspect, so don't remember details, but I do know that genetic diseases exist that seemed to have similar symptoms as your female.

Good Luck,
Dave
