As expected, there were a few bad eggs
Although I’m disappointed, I am not surprised at discovering the bad eggs today. I had a feeling that some would not hatch, I just wasn’t sure how many. As of today, I have officially given up on 8, leaving me with 13 still incubating. Of those, 9 look well developed and in good shape, 2 look like they have a fighting chance and the remaining 2 look to be on the downside. Given everything these eggs have gone through, I’m impressed to have nearly half that look as if they’ll hatch successfully.
Now that I know what to watch for in Trinity’s behavior, I hope to give the next clutch a better fighting chance. I check her each week at bath time and so far she has no indication that she’s carrying another clutch. But, when the time comes, I’ll be prepared… I already have a nesting cage setup.
In the next week or so, I will be preparing a baby cage. With the small number of hatchlings, I plan on keeping them in one cage together. I do have a few extra cages just in case there is a large disparity in size and I need to pull out the larger ones.
Today is day 42, so we have less than a month before the little ones pop out of their shell. I’m starting to peek in on them every other day to check for sweating and other indicators they may be ready to hatch out. I want to be sure to remove the lid in time for them to begin stretching. As we get closer to day 60, I imagine I’ll be checking on them several times a day. 
ok i jsut got two berdies and one had eggs i put them in the icubater but how do you tell if they are good if you cant see the embro
You can use a method called candling to see if the egg is fertilized. Take a small penlight flashlight and put it beneath an egg (this works best in a dark room). If it is fertilized you should see a small circle with thin veins near the top of the egg (the top as it was when your beardie laid it).
Check out the page at Milwaukee Reptiles for making a candling device and pictures of fertilized eggs.
