It has been many years since I have had Guineas. I had the best luck hatching them under broody bantams. The guineas I had were not reliable parents. I remember one guinea hen hatching 25 or more chicks. Within days she had lost most of them in the wet grass and weeds. The chicks could not keep up with the hen. Others brooded too with similar results. I pulled the chicks after that and raised them under a heat lamp. I found the chicks frail for the first week or so after hatching. Those that survived the first few weeks did well after that. I did use incubators and I think they are the same as incubating chicken eggs, but not positive.Hello! In spring I am getting a clutch of 12 eggs. I have hatched chicken eggs before but never guinea fowl. Any pointers on the differences besides the length? Also I would like to know more about brooding them. Thank you!
