There's good news and bad news regarding the kestrel. The bad news is that I candled the eggs we "rescued" from the nest box and they proved to be not viable. My theory is that when the female died the period of nonincubation was too long and they just didn't develop.
The good news is that the male found another mate and they have once again taken up residence in the nest box.
Meanwhile, since I now have the incubator I decided to try and hatch a couple of chicken eggs. It seems like not too long ago I had an overabundance of chickens. Then through one happenstance or the other, eventually I just had an overabundance of roosters. So we took care of that and now it is one rooster with five hens.
I put four eggs in the incubator. I know for sure that two of them are good. I'm not too sure about the other two.
Right now I'm going to take the chance that the other two are still good and won't explode into a stinky mess rather than destroy them and find out they were good after all. Chicken eggs take 21 days to hatch, so we may have Cinco de Mayo chicks. Stay tuned!
Here are a couple pictures of one of the kestrels. Or maybe one of each?
