Hi all, I've been lurking on this site for a while getting some great advice but only just joined. I've hatched two lots of chicks with my incubator successfully (tho the fox undid my hard work
), anyway I have a broody so let her hatch her own. Of the six eggs, two have hatched into gorgeous chicks, three completely empty, and one seemed to be a fully formed but dead chick. I've read lots of advice on why this might happen in an incubator but nothing in why it might happen under a hen? Any thoughts? I can post a pic but didn't know if that would be appreciated... Thank you.
The eggs that were clear sound like they were infertile if nothing developed in them at all. As for your fully formed that did not hatch I'm afraid this can sometimes just happen. What can happen in an incubator can also happen under a hen. I've just had 2 out of my last hatch that failed to hatch after pipping. One of the chicks pipped through a blood vessel and bled out and the other just didn't start zipping and died in the shell. Sometimes it's just the hand nature deals.
