My eggs were due for candling tonight, so I candled and took two out that were totally trasparent and sure enough one was a few weeks along ( I beleive it had alreay died from recent temp spike to 120 F) But the other was four days along and the light shined right through with no problem. And so I took them and cracked them open to wash down drain and I looked down and saw veins and a small pulsating dot in the middle And then the other a tiny little body with a head came out. I now just want to stop and throw out my incubator and everything. My one hen finally went broody after two years. So maybe just use her. At least I know my rooster is fertile. I QUIT!!!! AGGGGGHHHHHHHH!!!!!!!!!!!
