Yah, those dang Guinea egg shells are so thick and tough sometimes it takes a few good pecks (and a rest in between) to get a piece to pip outward.
For some reason I can't get your live hatching am to work, but I'll keep trying...Congrats on your hatch in progress tho!
2 of the handful of Guinea eggs I set with my Turkey eggs decided to hatch yesterday... 2 Coral Blues, 2 days before lockdown lol. I already moved them to the brooder because they were fluffed dried and running around in a huge hatcher all by themselves. I have another Guinea egg zipping now, tho this one is taking it's time. I wasn't planning on locking the Turkey eggs down until tonight, or maybe tomorrow AM tho. Oh well at least the keets will be eating drinking and running around really good by the time the poults start hatching, so the poults will pick up on how to eat and drink right away (hopefully).
