I rescued a egg from a abandoned nest in parking lot. It was a goose egg and the only one that hadn't been destroyed by a preditor. Anyway, I know the mom was sitting on it for probably 4 days or more. I started incubating it on March 17th. The last time I candled I saw movement so I know it is alive. So now my question is... when do I need to change the humidity in my incubator and do I turn the temp down. If I count the days its been in my incubator then I come up with the 13th. However, the mom was sitting on it for awhile.. do I start earlier?
