Brood #3 hatched 8/18/2017 Mama is a pearl grey.
Guess I did pretty good candling the eggs, when I said that this brood was a week behind brood #2.
Mama left the nest a bit early, there was one egg that was pipped. I put it in the incubator and a couple hours later, keet #17 entered the world.
They had a BAD night though. I had to put them in the chicken tractor because that was the only available pen I had, and there were storms forecast for the evening. I covered the chicken tractor as best I could with sheets of tin, but the wind, rain, and hail proved to be too much. At some point during the night, presumably when the wind got so strong that rain and hail were blowing sideways, mama guinea got up and moved. When I went out for morning chores, I was devastated to find 10 of the 17 keets laying flat on the ground, soaking wet, and stiff with cold.
I got a bucket and climbed in the pen to pick them up. I was shocked when a couple of them made weak movements when I picked them up, and one even made a quiet peep. I rushed them into the house, glad that I still had the incubator running. I put them in the incubator, went upstairs, and thought about the situation.
They were so cold, I didn't think they could warm up fast enough being held at their body temperature. Plus they were soaking wet... HAIRDRYER! Seriously, it was some kind of miracle to watch 6 of those 10 keets come back to life with the warmth of my hands and the hairdryer. An hour later, they were all bopping around and making my life difficult and jumping out of the incubator while I was trying to give them vitamins. I left them in the incubator all morning and put them back with mama this afternoon. At evening chores, they were all safely snuggled under mama. So 13 of the 17 keets have survived. As long as they keep eating and drinking, I think their prognosis is excellent.
