You're welcome! We did lose one chick, the one that hatched two days early. :( I'd hoped it wouldn't happen, because she was a feisty little cuss and the child of one of my favorite hens...but obviously something was wrong inside her, possibly something that didn't form quite right since she hatched before she was officially 'done cookin'. But we did have one last chick that hatched late, so we have four chicks again--three Americaunas mix and one kind of 'mystery' bantam chick--who has our banty roo, Scott for a father, but I'm uncertain of who mom is since the chick is unexpectedly very blonde. The egg was good-sized though, and I thought was from our Silver Laced Wyandotte hen. Time will tell when she feathers out more and we get to see what she looks like! I brought Moet, our buff Frizzle Cochin hen in as acting mom, she's raised chicks before and is an old pro. I wasn't initially going to do this, but the babies were peeping so loudly for US, that I wanted to nip that stuff in the bud. *L* But it's kind of cool to see the mom and kids interact. We'll try another hatch with eggs gotten from elsewhere, I'm afraid my girls are getting a little too old for their eggs to reliably hatch successfully (they are at least 4 years old, some are more like 6-7). But this time I was really trying to get some chicks from some of my favorite hens. I'm thinking I'll get some eggs from the local feed store, they've got some ex-battery hens, Cinnamon Queens, that look lovely. :) Velvet ~:>

Here's another real time eagle cam in Barttlesville with eggs also! Here is a link that might be useful: Sutton Avian Research Center

If you're seeing an unhatched egg five days after the others have hatched, it's probably a good idea to remove it. I've never had problems monitoring a chickadee nest. Sometimes the parent birds sit in a nearby tree and scold me, but that's about it. I would worry that as the babies move around more, the egg would break and foul the nest. I would wait for the female to leave the nest and carefully remove the unhatched egg.

Congrats on the new nestlings! They will fledge after 16-20 days. After they get to be 7-10 days old, they should be safe from wrens, so you can take off the wren guard. If you would rather keep it on longer, you should atleast take it off about 4 days before they fledge.
