red dots

[kidarcy]

can someone tell me what red dots in yokes mean? my wife swears they are unsafe to eat. also how soon should eggs be taken off nest after laying and put into incubator do determine successful hatch?
thanks

A red dot is more than likely, just a meat spot.. Completely safe to eat!! Eggs should be collected daily, sometimes multiple times daily if outside temperatures are excessivly hot, or really cold.. But eggs are usually viable for hatching for up to 10 days, sometimes longer, when stored properly. Hope this helps!!
