Baby pigeons stop being fed by their mother and start eating seeds

One of the best ways to try to get them to wean is to sprinkle the seed on the ground and not into a bowl. The roundness of the seed apparently kicks off the pecking instinct.

I've hand reared literally hundreds of pigeons over the years - as the bird gets to about four weeks old, I begin to cut the morning feed and leave them to peck around during the day as they get hungry -- it's really no different from their parents beginning to cut back on the feeding a bit as they get to about 34 days or so - I always give them a full evening feed.
