I've got 15 silkie eggs in an old Brower 845 incubator. It is working as I've seen development in most eggs that were candled so far. The problem is that it has a 2.5 inch diameter window, which is really to see the thermometer only. Someone loaned me a still air Hova Bator with 2 windows in the top. I'm wanting to heat it up (regulate temperature) and transfer the eggs on Day 18 so we can actually watch the chicks hatch. (Please, please hatch little babies ) The only thing that worries me is moving the eggs and wondering if that would damage them or something. So, please tell me what YOU would do (or what you've done). Move them??? or Keep them in the old one???
