I think I speak on behalf of all pigeon fanciers when I say thank you for trying to help a lost pigeon be returned to it's owner. Even if you've found a deceased bird, most pigeon fanciers are still interested in knowing what might have happened to their missing birds. Care Short term care for a lost racer is pretty simple. If a homer is off course, he's probably tired, hungry, and thirsty. A good meal and a night's rest might be all he needs to get back in the air and on his way home.
Pigeons are grain and seed eaters.
Other than a specially prepared racing mix, the best thing to offer a lost homer is a mix of wild bird seed and unpopped popcorn kernels. Offer water in a dish that's at least one or two inches deep. A pigeon dunks her entire beak in the water and draws the water up, rather than scooping like other birds. If the homer you've found is uninjured, do not continue to feed the bird. A healthy bird will be quite capable of returning to his home in time for the next meal.
