I am going to put in more guinea and chicken eggs but first i want oppions on what i should do.. I have an incubator that has three trays and a fan. last hatch i put in 24 chicken 78 guineas, terrible hatch 12 guineas hatched all had leg problems except 5 and now one is cracked which it should be fine too, 3 chicks hatched one survied the other two had the same problem as the guineas, bowed legs an toes. All but one chicken egg was fertile and i cracked them open to see went wrong some had quit forming really early others a few days before hatch time, i did this with my first half of guinea eggs the same thing, im not sure but i think its my incubator when it turns them it is very rough. My bedroom is on th opposite side of the house and i can hear it across the house. I was wndering could that be why the chicks stopped forming? And here is where i was gong with this... since i think its turning them too hard i was thnking of turning them myself, but can i turn the eggs and go to shool? Howoften should i turn? Should itbe around the same time?
