I have a wonderful broody silkie who was sitting wonderfully and then stopped. Like all together. I have already hatched 2 chicks from the eggs she was sitting on and they're are 3 left. They were place on August 24th according to the person we rescued the hen and eggs from. I do not have an incubator because I've done so well in the past with broody hens and I do not want to lose these chicks. She was off the nest approx 2 hours before we found her. I've got them in a box currently with a heat lamp with a temp of 94 and slowly bringing the humidity up. It's at 59% now. Do I need to go rush and buy an incubator? Or should I throw in the towel. I candled the eggs and they look normal, so I'm left scratching my head.
