i have bought an brinsea eco 20 and i thought most complaints were that it wasn't the best to hatch in so i bought a hova bator 1602N to go with it. i need to know if i still need to get the fan kit for it if i'm only going to be hatching in it. and what temp should i adjust it too. i'm at 98 right now. i'll be doing only duck eggs if that matters
