I've seen you do this on other threads. Is it a BYC feature? I'll get on the desktop and see if I can figure it out. Also, I did another egg and it looks like it died on day 17ish. I don't know why but it made me feel better! I guess like you said closure.
Trust me, if you use an incubator your face is glued to the window! So checking the nest box every 5 minutes would be totally normal! Just some advice on candling that far along, that helped me...was to shine the light into the air cell and just look for movement right around the base of the air cell. There won't be much to see throughout the egg because it will be filled with chick. But there's a small space where the inner membrane and air cell meet that you can sometimes see a little movement.Thanks everyone, I've been reading the thread for the past few weeks (I'm addicted to byc and all things chicken) I'm going to candle tonight and hope that there is life inside although I'm not completely sure what I will see seen as it should all be chick? Oh and seen as they are supposed to be in lock down do I keep them in exactly the same position I pick them up from? Part of me doesn't want to candle incase I make things worse but I'm struggling not to go put my ear against the nest box every few hours! All things being well I will post pics of chicks very soon
