I was given 4 turkey eggs last Saturday because the hen stopped sitting on them and the person knew I had a incubator. He didn't know how far along they were. I didn't think they would be viable however when I candled them - one looks to be about 2 weeks behind other three. I candled them again on Thursday and the three look like they are at day 18 but, I only have chicken eggs as a comparative for day to day development. How do I know when to start lock-down. I need pictures of candled turkey eggs past day 18. Can anyone help ?
