I'm getting my hovabator tomorrow and so I have a few quick questions. Do you NEED a wiggler in the hovabator? And where do you buy one if you do? And what department would I find the Hygrometer in? Does the thermometer in the hovabator work ok? I have the turner also but do I need to buy extras for a good hatch IE: a wigger or hygrometer/thermometer? Thanks for any help!!!! Almost forgot: If I only put 2 or 3 eggs in my hovabator would that harm the hatch? Does it need a certain amount of eggs?
