Any of those mini-LED flashlights work awesome too. I have tons of them laying around in the barn, in my truck, and even a lil keychain one.
I'm just kind of hoping less than half of mine hatch. On these first few batches, I cull out anything with improper toe spacing and stuff like that. Anything left over is held for fall show prospects. Its going to be alot of birds in the house for a few months. Later in the spring is when I really start hatching chicks to sell. Not really much of a demand for them until May up here.
