Hi all,

My Nosey Be laid 27 eggs on 7/2/12, how soon can you tell if the eggs are fertile?

I candled them and see nothing but yellow inside, and they are all white. Im assuming they have not gone bad yet.

2-3 weeks, if there not try will go mouldy an sink in

Just got a email from my wife and she laying another clutch as we speak hopefully they will become fertile.

if its past the 2-3 weeks and have not molded or sank in, its its safe to say they are fertile? what the time period you will be able to candle them and see vains?

Don't throw them out. Leave them in the incubation container until they go bad. I have had eggs go full term (10 Months), shrink/sweat and have nothing inside of them. They may not go bad for a while if the are infertile.
