A few weeks ago, I had a hen (buff orp) go broody. So, to keep her busy I stuck a couple of "refrigerated" call duck egss under her until my calls started to lay again. I gathered 2 more call duck eggs and put them under...3 days later, a friend gave me 3 RR eggs to hatch out. Well, on friday the chicks hatched out . I'm still waiting for the ducks to hatch. Meanwhile, the hen left her nest with chicks in tow (in a confined area) and I snatched the duck eggs and put them under a bulb late Sat afternoon. That night I returned the eggs to the hen who dutifully nestled and sat on them til this afternoon. She again left the nest to forage with her brood and I snatched them AGAIN. My point is... both the "refrigerated" eggs are chirping inside??? Plus the other egg that is there. I thought that chilled eggs wouldn't develop??! I'm thrilled, yet scared to death that now I have 3 viable eggs under a common lightbulb AARRRgh I'm trying to maintain a temperature they require. Yet am having difficulty with the humidity levels. I'm getting only 49% to 60% average on the ACURITE reading. Gosh, I hope I'm doing this right.... Any input would be greatly appreciated!!
