I am on Day 5 of a new hatch. I had all hatching very late on my last hatch so I had my husband bring home a therm from his lab so I could get a very accurate reading. I have it set at a height near the middle of the egg at 100F. (still air incubator) I was at Walmart and in the toy section yesterday and I came across a water weasel. So, I bought it and set it in my incubator next to the eggs for 12+ hours. I tested the temp inside it...and it is reading around 94-95. I have had late hatches, quite late so I did move the temp up a bit this time. I am very worried about overheating them. Do I trust the water weasel and risk moving up the temp or do I go with the medical lab accurate air temp? Thanks everyone.
