i had 2 sitting in the coop, one was sharing with a rir. lol she hatched none. the other hatched 2 by herself and both were killed. i dont know if she did it but i suspect. i pulled the rest of the eggs and most were not good a lot of them were in the wrong position and i had/have a staggered hatch. out of 40 eggs each hen, i got 2 from one hen and 5 from the single sitter. a lot of times they say they dont make good mamas is because if a keet gets chilled /wet it will die and mamas take them in the wet grass. they are an African bird so think of the weather/ climate there. the reason for the staggered hatch is because none of her eggs were good, the other guineas laid in her nest after she started sitting. they have to be able to hatch their own or there would be no guineas.I have had guineas for several years. I have incubated their eggs and raised keets and put guinea eggs under broody chickens and raised keets. Now, I have a guinea sitting on a nest of guinea eggs in my coop. I have never allowed any of my guineas to hatch out keets. All of their nests have been out in the elements. If I let this one do this, do I need to try to separate her from the rest of the chickens and guineas or will she be able to protect the little ones in the coop?
