Thank you for this thread! It gives me hope! Last night I took in 10 wild duck eggs that are due to hatch in about 5 days (duck nest in our front yard--we've been monitoring daily). The mother was gone for over 24 hours and I stayed up until 4 am last night to be certain. I then took in 6 eggs and left 4 in case she returned, but no luck. So this morning I took in the remaining 4. This afternoon I candled and saw life in 4 of the eggs. The other 6 still show red veins, so I'll check for life again tomorrow (trying not to handle them too much). I've been doing hours of research on all of this! It went down to around 50 Fahrenheit last night (when the eggs were still outside), so I was pretty excited when I saw some life today! I have them in a plant seedling tray with a seedling warmer underneath (buffered by towels). I'm also monitoring temperature and humidity according to research I've done. I plan to keep out of their sight, and hand them over to a wildlife center as soon as (if) they hatch. Any advice is welcome, as I am absolutely new to this! (Should I be starting a new thread?)
