I'm so glad to hear they made it through the night. Can a wild life centre take them?? I don't recall feeding cream of wheat to the baby birds that came in when I was a volunteer with the wild animal rehab I do hope that is okay maybe we didn't have any doves either. I was looking around and found this tid bit "Mourning dove regurgitates the food with a secretion she makes in her beak that contains more fat and protein than even cow's milk" Anyway good luck I'm keeping my fingers crossed.
[edit] I really don't know to much but this looked like it could be useful.
