I set 51 eggs in my incubator and I went outside and collected my hen that had been sitting on her nest for a few days. I put her in a cage inside and gave her 12 eggs...... she pushed 3 out and let them go cold an to my surprise they were empty, she had 9 left and she has sat on them very well, hot days and all. 89*F for the past few days. One hatched under her at day 16 and one hatch today on day 17in the incubator. i transferred that egg to the chicken as she already has a chick from the day before.. we are on day 18 in the incubator and the eggs under her as well. she has 8 eggs under her and two chicks One more day and i can shift the turner out and let the eggs sit on the floor of the incubator to hatch out. has any one else come across a chick hatching 5 days too early?
