Ok, let me explain this clearly for you. FIRST IF you don't know how to care for a baby bird, it can be deadly IF you don't feed it properly! Second, you need to watch some videos on how to handfeed and the consistency of the formula should be when you mix it. Third, run to your local hardware store and get one of those clamp on shop lights, they're NOT expensive at all, get you some 60w bulbs, get a 10g aquarium and place bedding on the bottom. Place the light onto the aquarium and leave it on 24/7 on one side of the tank and cover the other side of the tank with a towel. So if the baby gets hot, he can move over to the side that's not as hot which would be the side being covered by a blanket. This would be your brooder! At 2 and a half weeks this would do, if younger, you would need two shop lights with lights on. I put filtered water in a cup into the microwave and bring it to boiling point. Mix one and a half teaspoon of formula in a clean container, place formula in first then put little water in at a time to and stir it while you put it in. Mix it to a oat meal like consistency to a little more liquid like where it's not too thick. Then keep on stirring with the spoon until you get all the formula properly mixed in. Let it cool for about 5 min. You can feel it not hot to the touch, it should be luke warm. At this stage, I didn't even feed every 4 hours, but if you don't know what your doing, this is probably best to do by feeding what the baby wants to eat. I feed every 12 hours, once in the morning and once at night. You can check the crop sack to know if your doing the right timing. Crop sack should be emptied every time you feed. There's danger in this as well, especially a lot of folks experienced this for Kaytee Exact Formula including me is that the formula tend to go hard and the baby not being able to digest. So it is quite important that you know what your doing!!!! That's why the posters above told you to bring him back. IF your unwilling to bring him back, at least bring him to someone locally who knows what they're doing and show you how it is done properly! Even feeding with a syringe improperly CAN kill a baby bird!
