Eastern Box Turtle Eggs. Collapsed? Help!
I just collected some eggs from my Eastern Box turtles, and have a question.
I have 12 Eastern Box turtles. 9 females and 3 males. They are kept outdoors all summer long. The temps around here have been 85-90 degrees with lots of humidity. (Michigan)
I collected 7 eggs. 1 egg from one turtle, and three each from two others. 3 seperate clutchs.
I put them in a tuperware with vermiculite and moss, put a heat lamp on them witha a thermometer, and kept them at 85 degrees, and misted them a few times each day. I keep the house air conditioned at 74 degrees, but the thermometer that is sitting with the eggs has been kept at 85-87 degrees.
After two days, six of the eggs, all three from each of the later two clutches partially collapsed. It looks like someone took a finger and just pushed in the side. The other one egg is fine. Still keeping it's shape.
They did this two days after I collected them, and I collected them the morning after they were laid. I watched the females digging the holes the night before.
They eggs were handled very gently, and were not tipped or rolled around at all.
I have read that they can have "dents" in them, but these are pretty severe. My guess is they are bad, but I am gonna keep them until I know for sure. Mainly, I want to know what I may have done to cause this, and how I can prevent it with eggs in the future.
Any input or advice would be great.
