I have posted this before but never got an answer...I have 3 pekin duck eggs (first time hatcher) and on day 11. 1 is growing and moving around like crazy, 1 I can't see an embryo but it is has veins, and 1 has never had any veining and is more of a yellow color when candling (never saw an embryo). I have been candling every other day. Just wondering when do I toss an egg that I don't see developing? I have small chickubator so I could use some extra room in there for "lockdown". Thanks so much in advance for your help! p.s. I'd be happy to post candling pics if needed!
