"But the first five eggs appear to be bad"
In person, two of them are tan/little brown, but the other three look white, just covered in lots of sand and dirt. They all may be no good, but I will incubate them any way. If anything, I will learn and gain experience.
"Let me take a wild guess, the last two eggs were laid after you dug up the first five. Thats why they are clean and white."
Yes and no, she laid them after covering the nest, but before I dug anything up. She laid them on the opposite side of enclosure, above ground after she had a drink.
"Now that you had them nest, you need to understand because they did, does not mean its good or sufficent. You do understand if you kept the cage dry they will nest in the water bowl."
The vertical depth is about 12-14 inches where she laid. I would estimate due to the angle and elbow at the end of the tunnel, and by her length, the whole tunnel and egg chamber was about 3 feet long.
You metion, if the cage is too dry, does it look to dry? In the photos you can see the darker, wet dirt she dug up. I know you are not one for measurements, but the cage humidity on the hot side is about 65-85%, and the cool side in the 90's, and after lights out its about 99% everywhere. I get condensation on the walls, I am afaid if I made it wetter it would be a swampy bog.
As always, I welcome good constructive advise and reviews of my efforts, its the way I learn. Research, trial, and error, and trial some more.
Thanks Keith
