Straight up the only way a chicken hen may lay two eggs a "day" is when a day is 24 hours long and the egg process is 20 hours long.
Technically you would collect ONE egg immediately laid by a hen and start your 24 hour DAY of time clock ticking. Then you need to be back some time AFTER 20 hours (but not over the 24 hours to equal one day) has passed when that hen has done her 20 hour egg cycle to find she has laid two eggs in YOUR 24 hour cycle for a day.
ONE egg laid and then 20 hours to make another, that DOES = two eggs in a 24 hour day cycle, but the timing has to be impeccable for us cackle berry collectors to witness when our hens are capable of two eggs per 24 hour day. I too have had two eggs laid by my hens in a 24 hour of one day but I agree with CC that 20 hours is your average time period that a chicken hen needs to produce each egg.
My head hurts! I do believe I have not had enough java in me yet.
