Chicken Eggs

One or the other of these is a bug. I get egg hunt option 2 days after the last time I harvested eggs. Someone said it should be 3 days-so the fact I got eggs on day 18 and 20 would be a bug if so. Otherwise, I had noticed a 2 day per hunt...however, if you delay hunting a couple of days, it doesn't "build up" as it's supposed to. If you wait 5 days, then hunt, you get it 2 days afterwards, rather than immediately due to the "build up".

I meant of chances. I thought that if you say, went out of town for 10 days, you should ave 3-5 "chances" built up for egg hunts that you can use 1 per day. With appropriate build up after. Does that mean you just get an egg hunt 2 days after last, and thats all then? And thus need to get a hunt any day you have to maximize profit?
