Please help! Sick pigeon baby?

[Angelika]

A pigeon baby hatched on my balcony nine days ago. It seems to be breathing very heavily alfor at least three or four days. It is actually panting with its beak open all the time, making tiny labored noises. Mom and Dad have all in all been very caring, but tonight neither of them came back to the nest. I've taken the baby in over night and tried to feed it some baby bird formula (with little success). I had hardly more success with trying to open its beak and looking into its throat. Fromthe short glimpses I had, I could see nothing conspicuous. The tip of the tongue has a bluish black tinge, but the tiny one is totally black-skinned (and black-feeted) any way. There seems to be a little sour smell to its breath. But I am not sure. This is the first time that I am observing so small a pigeon baby, and I simply do not know what is normal and what not in such a fragile little bundle of life.
It's about a year that I became a real pigeon lover. All I have learned in the meantimeabout the birds I thank to your web site. I have taken in some older babies (3-4 weeks old) and a number of very sick pigeons (also mostly youngsters)and tried to help them--with mixed results. Some of them recovered and urgently wanted to go back to their peers again, some died. One youngster, now six weeks old, has strongly bonded with me and might be staying with me. I have a stash of important pigeon medication, but my experience is entirely insufficient with this nine-day-old baby. I hope I have not done anything wrong so far. Please help!
