I agree, guineas are not good moms! I hope I don’t end up with dead keets again, but integrating last years babies into our current flock has been ridiculous! After 9 months, I still have two different flocks forced to unhappily live together... I’ve have to temporarily pen them all up together after a recent bobcat attack, and I’m afraid one will get killed by a rival guinea!I had to do the same with my turkeys. One hen would set and the others just kept adding, and adding, and adding... I learned to mark initial eggs then remove anything that wasn't marked or I'd a get a hot mess really fast.
Though turkey moms, guineas too (I used to have them) are not good moms so I would remove anything that hatched and give it to a broody chicken hen.
