I took another pic of my eggs so you can see how I have them marked. They a pretty dirty, the week they were laid it rained everyday and the ducks are free range so the laid them under the porch in the mud. Nothing is caked on, just stained by the red mud. I'm debating warming up the other incubator and splitting them up for lockdown?? I wonder if it would make a difference to give them more room for hatching??
