Hi! I'm kinda new here and I have a bit of a question. I have 15 silkie eggs in my incubator. (Brinsea Eco 20) My friend gave me 5 duck eggs as her dog killed the mother .. I discovered only two of them were alive so they are currently in my bator with my chicken eggs. Day 21 for my chicks will be July 12. I hand turn 3x a day. Trying to guess what stage the duck eggs are at but in stumped. They have a small air sack at one end and veiny and dark in the rest. Definitely movement. I'm just wondering the best way to go about turning and lockdown for the duck eggs? Obviously I don't want to ruin my chicken hatch so I am going to continue to turn and lockdown on day 18. What would you do? Will turning the duck eggs up until they hatch harm them? Thanks for any insight!!
