I have a pair of opaline guineas i hatched july of last year. For the past two to three weeks my female has been going under the nesting box and making the nesting call (looked it up on youtube) and she stops if i peak around the corner at her. She even rolled a duck egg into the spot and was sitting on it. But still no eggs. Is she sick? Or do the females just do this alot before starting to lay? If so when will she start to lay? I have a bad snake problem an egg can't be on the ground for more then 12 hrs without a snake getting it so i wanna replace her eggs with golf balls as soon as she starts laying.
