Hello and welcome to Pigeons.com. Thank you so much for your concern for the two young pigeons. Are they
fully feathered, including under their wings? Do they still have tufts of yellow down, especially on their heads? Are they squeaking or cooing? If you go to the home page of this site and look at the "Baby Sara" photos you should be able to estimate how old your youngsters are. Click on the "Basic
pigeon care" link for information on feeding young to adult pigeons.
If they are almost fully feathered you can try offering them pigeon mix (best) or dove mix from the pet store or unpopped popcorn. Sprinkle it around and they should be curious enough to start pecking at it. Provide them a container of water at least a couple inches deep and gently dip their beaks in it to show them where it is. You may have to do this several times, but they will learn quickly.
If they are still too young to eat on their own, here's a link with detailed instructions on feeding very young pigeons.
