I have an australorp that insisted on going broody, it had been trying off and on for weeks. Finally I gave it 3 eggs on June 10th, and it's been sitting on them since. The other day I found it had changed nests, and was off the eggs for long enough for them to get cold. I moved her back to the correct nest, but found her moved again the next day. I moved the eggs to under her where they have been since. Would the eggs she's sitting on still hatch even though they got to "room temperature" a couple times? I candled them last night and they clearly are (or were) developing. Also, the nest is up high, and my early attempts to move her to a lower box failed repeatedly. If/when they hatch, what's the best way to move them and mamahen to a safer place?
