I bought a Fluker Temp/hygrometer today, since so many members recommended it. Now, will the batteries last for 25 days of CONTINUOUS use. So that I can turn it on before I set the eggs and have it run until I remove the chicks?? And I will be setting Serama eggs, which are quite small. Do you think I could just attach it right to the turner next to the eggs?? Where do you place your Fluker???
