hello 
recently my one pair of cockatiels made a nest under a dresser we have been using for a stand, and they actually managed to hatch an egg. Here is the issue.
Tonight when my wife went in she came out with a mortified look on her face and told me there was a dead baby bird about a foot in front of the stand. When I went in it was not dead but had rolled itself out from under the stand. So I quickly put together a makeshift nest in one of the drawers out of the dresser, the mom watched with great intent. I transfered the remaining egg in as well as the nesting material. Then I got another of our cages(our birds free fly in a room that is their aviary) and transfered both parents, the baby and the egg into the cage and covered it with a towel.
My ? is is there anyone on here who has experience with feeding a day or two old bird if the parents reject it, since I had to touch the bird to move it, especially because my other birds were eyeing up the baby as a snack.
I am about to do a net search for info as well. None of my tiels eggs have ever hatched before. I did take one picture of the baby did not want to bother mom to much.
And help will be appreciated. ie what to feed etc....
