I am new so forgive if Im doing this wrong. I have had feral pigeons for years now and all of a sudden they couldn't fly and their heads were spinning around. It was heart breaking. The ones that I caught around 9 of them I took to a wildlife rehab. vet. The man I spoke too said they are spinners and was probably genetic. If its genetic then why do they all get sick at the same time? Another lady at another time said it was avitrol poison. So many died and i still have 3 in the house. I had one of my fav's Walter in a cage for 9 weeks and he flew away just fine. I was so happy. The three i have im not sure if they can fly yet. On next door.com a man was bragging that once he feeds them they dont ever come back....poisoning them? Has anyone else had this problem? All my neighbors hate pigeons and rats. Sprinkling rat poison on fences to get rats and so far one dog has died. They are so careless with poison and dont think about the second hand poisoning. I almost quit the nextdoor.com cause people were so mean to me about the pigeons. I have always loved them and always will. I live in Las Vegas Nevada.
