Does she look broody?Ohh gotchu, yeah i was told differently lol. But yeah i have seen them doing the deed so hopefully they are fertile but should i do something to keep the egg warm or just let her handle it on her own?
If not you can keep the egg in a cool 45 to 65 degrees, area of the house for 2 to 3 weeks in a egg carton pointy end facing down, before incubating.
That gives you plenty of time to get an incubator.
