Hi, basically as the title says I have an egg in the incubator and it's only been in for 3 days but when you candle it it looks like the air sac is on the side of the egg rather than at the end, will the duckling still develop?
You're more than welcome. Good luck and let us know how it goes. Watch your humidity and don't let it get too out of control. The greatest concern is the chick drowning when he pips.
