Old fishtank as a incubator? I mean if you can keep it warm in thre for Reptiles. why not for eggies. like the bottom with a soft towl or soil to Simulate a nest. run your light and such in it I have a old fishtank and it be neat to use that, then i'd not have to worrie about peeking as i'd have a 100% view at all times. and thank god i have a HUGE garden tub. that I can use for a brooder after they are a ilttle bigger LOL. just currious.. as I'm planning on somday attempting to hatch eggs.. thought it be fun. esp with all the breeds out there. I'd love love love to hatch a couple silkies.
