my muscovy eggs should of hatched 7 days ago from what I gathered from when mamma started sitting on them. I have candled all of them after finding her to have no interest in them and when I picked them up they were cold. There is life to most. How do I incubate them?we have them in there and I know they are hard to hatch but I would like to give them a chance. Our days are getting colder to. Any help would be great!!
