Ok, here is what you need to know. This bird is probably about 4-5 days old I would suppose, seeing that the eyes are open and it is still small. The bird I have right now is about just as old. Here is what we have been doing for our bird:
Food: Kaytee Exact Feeding Formula for baby's birds (feed him about 5ml of a solution of 1tsp of powder to 2-3tsp of moderately warm water three times a day. Gradually increase the consistency of this soulution to about the consistency of ketchup after the squab is 5 days old).
Heat: use a 40w lightbulb red heating lamp or you can use a heating pad set to low with a thin blanket set on top of it. The bird needs to be kept at about 90 degrees Fahrenheit until it is two weeks old.
Feeding: get a 10ml medical syringe and cut off the end at the 1ml line completely. Then to feed the bird, bring the syringe plug back to the 5ml mark and fill it with the mixed solution. Next, grab a rubber balloon or a laytex glove and cut it in half completely so that you have a thin rubber surface. Then, place that over the open end of the syringe, making sure the ends of the rubber surface of the balloon are around the outside of the syringe and take a rubber band and wrap it around the ballon four or five times. Then take scissors and cut a slit about as wide as a fingernail in the top of the opening. Finally, hold the bed in your hand with a paper towel and guide the bird's beak into the opening and it should eat on its own (that is if the bird is squeaking. I doubt it isn't, considering how old it looks to be). Do this 3 times a day. Make sure to let the crop (the underside portion that will look like a balloon after you feed it on the breast area) empty completely (go flat) once every 24 hours as not doing so will build bacteria inside of it and produce sour crop. Also, always make fresh food. If you make it prior to feeding the bird in large batches, it will go sour.
Enclosure: get an empty 1 gallon plastic circular water jug and cut the bottom off just an inch or so under the halfway mark of the jug. Then fold a rag or kitchen towel twice. Finally, place it itnside the cut off bottom end of the jug and make sure the towel is touching the sides.
I pray to Jesus this helps out! There are many websites that are able to help out with this stuff too, however you have to look around for them. This is not a set standard, but it's what I've been doing. We found our bird about 4 days ago and it must have just hatched when we did. Anyhow, I will post pictures too so you get an idea of what it looks like.
"All praise to God, the Father of our Lord Jesus Christ. God is our merciful Father and the source of all comfort. He comforts us in all our troubles so that we can comfort others. When they are troubled, we will be able to give them the same comfort God has given us" (2 Corinthians 1:3-4, NLT). .
