I have a large clutch of guinea fowl eggs in my coop. I know they say that guineas will wait to set until she has maybe 30-40 eggs!! So my question is, if I want to incubate the in an incubator how long can wait or how long before the eggs are no good. If a hen is only laying 1 egg a day and she doesn't set till 30-40 eggs later that's a good month. Do eggs last that long. I just wanna know safe time for eggs being put into bator. I don't want to set a bunch that won't hatch! Thanks to anyone who can answer this for me!!
