I bought an incubator today, now all I need is a hygrometer and thermometer. and Patience!!! I want to go out and get some of the hens eggs but it is so cold I would have to get them probably within 10 min of being lain. This weekend it is supposed to be -7F one night and -10F another night. .Then I do need to separate by breeds also, I better do that because I will still have to wait 3 wkS?4wks?
