I'm finally able to try again after a dismal hatch last spring. This will bein a preschool I can access 7 days a week. I bought a hygrometer to better measure the humidity. What's the best thermometer situation? Something I can use with an automatic turner... We're using a hovabator. 24 eggs collected by a lady who sells them fir a living. I recognize that at this time of year we will be looking at a decrease in fertility. The eggs will be 4 days from collection. Stored and turned appropriately until being out in the bator. Last batch I got 0/24 so I'm looking for any tips I can get. This is my second hatch. Thanks so much for any advice!
