Hello all...is there some sort of hydrogemeter I could pick up at a local walmart. I have seen them there, but not sure if they're good or not and if any of you could recommend one or a specific brand to me?? I have three hovabators fired up and just curious on maintaining proper humidity. I always just hatch eggs and usually have good success. Just thought I might have even better success if I kept better humidity temps. Any advice would be great! Thanks SO much!!!
