My wood duck laid a few eggs a couple weeks ago. Unfortunately she laid most in the pond and only one in the box. She apparently had been incubating the one egg without me knowing for a little while. I took the egg in hopes of having her lay another clutch that was hopefully a bit bigger. When I started incubating the egg artificially it already had some veins and the beating heart was just barely visiable. The egg has been progressing well, but I am wondering at about what day the egg may have been when I put it in the incubator? I put it in on 4/2 so I am wondering when I should stop turning? I am thinking I should be pretty close. My guess for hatching day is 4/25
