Hope that this works and will download. Click on egg and it takes you to my photo bucket. it is a short video I did of an egg in my bator. Here are some pic of the bator that my DH and I built. It took us two weekends because I wanted to stain and put some finish coats on it to seal it against moisture. Then I made the trays and we let it set to cure the finish. I did not want fumes from the finish to mess up the eggs. Outside of bator door locks fan and heater hatching trays on bottom turning trays on top egg cartons in incubator rotating trays. I can put in 180 eggs at a time if I had them. That will come in handy when I have more chicken or do staggered hatches.
