I've got a homemade incubator that's been giving me a world of grief! The first few hatches were great. I had so many chicks I didn't know what to do with them. Then all of the sudden my hatch date fell to around 20-25%. I don't know why. Nothing at that point had changed. Recently, I've had numerous eggs pip at the wrong end. I know its not the chickens or the eggs causing this. The eggs were fresh. They came from various coops from my house. Its something to do with the incubator. Can anyone help figure this out. I'm almost at wits end.
