In late April I purchased three adult guineas. They were "supposed" to be 8 months old and 2 girls and a boy (based on physical features, I do think it's a trio) Finally, within the past week I have started getting eggs. I find one every day or two (they are still caged, for now) but the eggs are unfertilized. Do females mature faster? or Is there any other reason that one female would lay and another getting the same care and in the same condition wouldn't? And that they'd be unfertilized?
