Yes, with 2 Hens on the egg pile there is more of a chance that more eggs will get covered and hatch out (if a predator doesn't get them both!), but the Hens may still get off the nest together after the first few eggs hatch and leave the rest, so you still may want to keep a close eye on the nest and have your incubator ready and be ready to rescue the eggs that are left behind, starting to chill/go cold. They can die pretty quickly (being cold overnight would most likely kill any developing eggs).I have decided to leave dedicated guinea alone with her insane amount of eggs. She finally come off her nest this morning to eat. This was the 1st time I've seen her out of the nest since she started sitting so I was not sure if she was going to go back. I had decided if she didn't no biggie id take the eggs candle and incubate. Went out for my evening rounds and discovered she has company. Another hen has went and started sitting with her. I think its so funny. I wish I could post pics! There are definitely more eggs being covered lol maybe usng the buddy. System while setting together will make them a little safer? And give more of the eggs a chance? If not at least she has company? Lol
After the Hens are off the nest with their keets, containing both Hens with the keets (where the rest of the flock can see them, but not get to them) for the first couple or few weeks will help insure the survival of the keets, because they are really fragile right after they hatch. The Momma Hens don't always tend to the keets very well like a chicken Momma would, so if you can get everybody situated in a small safe area your keets stand a much better chance than if you let the Mommas go traipsing around with them as soon as they hatch. Depending on the area your birds normally free range, some of the keets may end up getting lost, stuck somewhere and left behind, wet/chilled, picked off by predators etc... so IMO it's best to keep everybody contained until the keets are a little more hearty and less fragile. Plus you want to make sure they get a good start with high protein game bird starter.
If you do end up incubating a bunch of the left over eggs, the Hens and flock may not accept the incubator raised keets after they've hatched if you try to give them back to them, so they may need to be brooder raised or 5-6 weeks before you'd want to section them off out in the coop so the older birds can all get used to them, but not get to them or hurt them. Sometimes flocks will kill new birds because they see them as a threat to the flock, or their pecking order status... who knows. They can be especially vicious to younger additions, whether they came from their eggs or not. And some birds/flocks will even instantly kill newly hatched baby keets. It doesn't happen all the time like this, but it can happen... so it's always a good idea to be prepared for the worst. I've seen way too many posts where people post about proud Momma Guinea Hens starting out with 16 or so newly hatched keets, and end up losing them one by one over a couple days time until they have none left. Sad, especially when it can be prevented...
The buddy system with Guinea Hens is common
