This is my first time hatching. My hen abandoned her eggs a few days back & I'm trying like crazy to save these babies ! I lost 3 of the 6 so far Of the 3 left, 2 look like they * may * have internally pipped, from what I've seen from pics ? Today, one is tapping inside of his egg. Is this something bad ? What should I do from here on out ? I have no incubator because I never planned on this, just one I kind of rigged up, with a heat lamp & a bowl of water. I also spritz the eggs often. Thank you so much for any advice !
