So those of you that hvae pigeons or have had one does this one look healthy? I know it might be hard to tell from a picture but after reading things about pigeons and the diseases they can carry it worries me it might be sick. It eats and drinks fine and also seems to have no problem using the shed, sidewalk, and steps as a toliet. It still worries me why he ended up at the church and why he does not fly any higher than what he does.
If you are concerned if he has some type of disease take the following action:
Examine the birds stool, is it runny and/or greenish in color? If so obtain some Sulmet
from your local feed store and feed it 1 tsp daily in its water for 10 days. This is twice the required treatment period but some bugs are becoming more stubborn. Sulmet is a very good general animal medication that can be given to every animal on my farm from pigeons, chickens, turkeys, guineas, goats, and sheep and cattle, pigs, and horses as well.
Being a feral pigeon it is more likely a courrier rather than active infection. Most diseases that affect pigeons are not transmittable to other poultry with the exception of Parathyroid. Personally, I am of the opinion that the bird has incurred some injury that limits its flight ability. I can't see the right wing in any of the photos but I suspect a slightly lower holding of that wing comopared to the left wing. Also, even a foot or leg injury is enough to impede a pigeons flight.
