Well my dad was on the job and sent me a text message with a picture of a nest with five sparrow eggs in it, he said he knew it was a sparrows nest because the sparrow flew out and hit him on the head. When he came home he was telling me about it and right away I asked him if he had touched it and he told me that he had to otherwise it would've gotten shumshed...So then he and I went back down the raod where he found the nest and we brought it back home. So now we are going to try and hatch these babies, except, I need a little help...How long does it usally take for them to hatch? There are five eggs, what percentage of the eggs usally survive?? Do we need to go buy a special heating lamp? Any help you can give I would gladly appriciate!!!!
