I think incubating at this time of year would be slightly early, the electricity bills would be through the roof, because you have to have a lamp on full time, when they're growing. Having said that a lot of people do incubate this time of year and it works well. If you started the incubation today, then count 21 days from now to hatching, plus a few more weeks under the lamp, plus getting them used to other foods, gradually introducing them to a big shed, or pasture; You might very well do it, some hens however are sold POL and don't start laying till early summer, so it really depends on everything, plus the breed. Sorry I can't be more helpful. Do let us know how you get on though?
