I'm pretty new also but I've had awesome success from my bees. I waited till my first 10 Frame deep box was 80% full then I added another deep box. The first year they filled both boxes. I removed one frame of honey for myself and left the rest for them. I live in southern Louisiana so my winters are mild but I left them two boxes anyway. My hive is three years old now and I think it's 5 boxes high. Only the bottom two boxes have brood the rest is honey. I've harvested 30 lbs so far this year and have two deep boxes left. I'm no pro for sure but my bees health for me was more important than honey the first year. Also my hive is treatment free except for oil under my screened bottom board.
