I have been running it empty with water in the outside slots for 5 days. The temperature has varied by about a degree depending on the time of day I check it. The thermometer is laying on the wire and is at 99.00 pretty constant. Any suggestions before I set my eggs?
Jeffers is the only place I've found online that sells it. Once you mix the sterile water it needs to be used within an hour. I have cattle vaccine the same way. The label information is on their site. 20-22 gauge needle with 3/8-1/2" length.
Hope this helps.
