The best thing to do in the park is avoid feeding the pigeons at all. Otherwise you will be covered in poop and birds. If you are raising pigeons then grains are the way to go. Corn is especially good for them in the winter months but should make up no more than 30% of the mix of food. Corn is stored in the body as fat so you don’t want to over feed corn. Pigeons also love field peas and they are good for the bird. The peas will help build strong muscles for the birds.
