Which upgrade should I get first?

[Faverolling]

What incubator upgrade is more important, egg turner or a fan?

I will be getting both eventually, but which should I get first?

Egg turner as it saves you time and you do not need to open the incubator several times a day the fan can wait if anything needs to wait but you will need to keep your temps up to 102F with chicken egg's and for other eggs check your guide......
