guinea eggs...I think I have done better with them than duck eggs! Well...I know I have. Never done anything special...just remember they take a little longer to cook. We hatched out like 100 or so last year...the only hard thing is finding where they lay them and getting them n the bator! Those dudes can hide an egg. I set 48 last night. Took my buddy awhile to find the nest so we are hoping they aren't too old!
