Hi guys, I have a question. A couple of my hen went broody (LFSF). What started as a four egg nest grew exponentially because Buffy was stealing eggs AND other semi broody girls were laying in it. Hatch date for the first four came and went so I was just going to destroy the nest. There was a broken egg that morning that looked to be about a day 15 chick. So I held off.
In the interim Sookie started sharing the nest with Buffy. They divided the eggs when both were sitting ( there were 17 eggs EEK) and one would brood the nest in turns while the other took a break. (Buffy had been on the nest for 35 days and stuck tight). I thought the tandem brooding was kind of cool, since i had little hope for any hatching left them to it. My nest boxes are very large and have more than enough room for two to sit comfortably. I tried splitting the nest in two but Sookie moved them all again to the other nest.
Yesterday I had a chirping egg! I was over the moon! None of the eggs were pipping so I figured maybe today or tomorrow. Well, this morning I had a dead chick in the nest

. I was so upset. I know it happens but I was terribly saddened. So on to my questions...
It got quite cold here last night and so I am guessing this is the reason for the chick's untimely demise as it was not damaged in anyway. First, a friend is giving me a thermal air hovobator. Can I move the rest of the eggs to the bator when it gets set up or is this hatch just still pot luck.
Next, Sookie has consumed all of the polish eggs that were in that nest plus a few others. The polish egg that should have hatched about now was cracked during her moving it from one nest to another. The other polish eggs were past hatching. Yesterday, there were 14 eggs. 14 has turned to eight with one hatch and a cracked one on the floor so 4 eggs went down her gullet. I blame her because I saw her eating one. I don't think she is cannibalizing for the fun it. She takes very good care of the eggs. So... Is she eating eggs from other hens, is she just shrinking the nest to make it more likely to hatch OR can she tell these eggs won't make it and is just disposing of them?
I have obviously never hatched eggs before. Any help is appreciated. I will have one million incubator questions that will go in an incubator thread as soo as I see the thing.lol. I have no idea what to expect.
