Elana,
I think they're a write off too, especially if they have to be kept at the temps Debbie said. It's just so frustrating
I'll give the blue hen one more shot for this breeding season.I can't imagine having to explain that to young elementary students, especially seeing it first hand at a zoo! What did you do?
Debbie
Thanks so much for your info...I think the eggs are probably done for...I just got home, and it's obvious the societies are not interested in the nest at all. I guess it was worth a shot
I might wait a couple more days and then candle again to see if anything is forming.
So now, I'm gonna see if the blue hen will lay one last clutch, and swap them out with the fake eggs in the society nest.....third times a charm 
.
I knew the male had been sitting in the nest off and on, but I hadn't seen the female sitting at all. I'm not even sure if she's finished laying eggs at this point, but not wanting to take chances, I went ahead and pulled out the eggs in the society finches nest, and replaced them with the gouldian eggs. I held my breath to see if the societies would sit, and four were in the nest within five minutes, sitting comfortably 
It was kind of hung up on the cage, and when I lifted it off the cage bar, it popped up really hard. I don't think the blue hen is done laying eggs...her tail kind of keeps bobbing up and down, which is what it did with the last two clutches, and then when she stopped laying eggs, it was normal. Maybe she'll lay one or two more, and I'll leave those in there.
