OK- I started 21 days ago with 12 eggs. By a week ago we were down to 3 (2 FBCM, 1 Lav Ameraucana). I had a silkie and a blue orpington (Helen- has had cataracts since she was 6 mo old, partially blind......can still eat and get around but she misses when she pecks sometimes and occasionally stumbles off low drops). This is the first time letting her brood. She is about 3 years old. They had already been broody a few weeks when I took the jump and ordered eggs. After losing 9 eggs- found some broken shell, never found the others...suspect she ate them once they broke or something (yes they are isolated in a very small coop with no holes) I kind of decided it was very unlikely we would get any chicks. Yesterday she was off the nest a lot. Even laying out on the coop floor once. The silkie stopped brooding about 7-10 days ago but I left her in there because she did sit in the nest with Helen at night and I figured 2 warm bodies were better then 1. Well- today Helen was off the nest for over 3 hours. I decided to feel the eggs- they were pretty cool. I brought them in to candle to see if there was any hope. Couldn't see in the darkest one. Could a bit in the lighter brown one- good air cell, veins....maybe movement but may have been my imagination. Started on the blue one- good air cell......it started peeping! Set up the incubator. Popped them in- but I REALLY don't want to hand raise any chicks right now. Put 3 similar unfertile eggs back in nest. 30 min later......Helen was sitting on them! Swapped them with the fertile ones. Helen stayed on them another 1/2 hr or so....then back off and now has been off for a good 45 minutes. Sigh. My thought is to let nature run it's course......but then.....Grrrrr.... Advice?
