My momma guinea was sitting on a nest of 17 eggs and only 4 of the chicks were able to break out of the shells. All the rest of the chicks had little beaks sticking out of holes in the eggs but never made it the rest of the way out. Does anyone know why this would happen? My guineas are free range and the hen was sitting on a nest I didnt know she had until she came up to the house with 4 chicks. I went searching for the nest and finally found it today. Of course by then it was too late to help the remaining chicks. I caught the mom and the 4 chicks and put them in my brooder. Ill keep them there until the chicks are old enough to fly out of the brooder on their own and follow their mom. That seems to be the only way to keep the chicks alive. If I try letting the mom raise them on her own the chicks dont seem to last more than a day or two. But Im at a loss as to why the chicks would not be able to break out of the eggs.
