Buying fertile eggs

[Spunky1]

I have decided to get some fertile eggs for my lone hen to hatch to get a new flock started. This will be a new experience for both of us! My first of what will probably be many questions over the coming weeks, is, how long does a fertile egg stay viable before it needs to go under the hen?

The link above should give you all the links/info you could ever possibly need. I used the information there myself the first time I incubated eggs. I believe they're good for roughly a week before the chances of incubating go way down, but I would reference the link for tips from real experts. XD
