My rule of thumb is never expect a honey harvest the first year.
That is fatal rule even if it is true.
If I have 3 lbs bees (swarm, or package) is difficult even to me get honey firts year.
When I put 6 lbs package into Langstroth box it is able to raise honey hive and even get another nuc later. 6 lbs occupies whole box but 3 lbs only half. It takes 2 month to get hive in yield condition.
Important thing is that beginners are mad to fill combs with sugar. So new hive has any more room to raise brood. If you feed all summer, it is not honey.
I am able to raise 2 frame nuc to get 200 lbs honey first year but it needs one box full of bees from stronger hive. And one box is not enough.
I need another box that 6 weeks before mainflow I have 2 box full of brood. And I need electrict heating too into hive bottom. It fastens build up a lot.
Nucs are better than packages. They are 3 weeks ahead of mere bees.
One full comb of emerging bees produces 3 frames bees. It needs 4 weeks time because older bees die at same time.
Main difficulty for beginners is that they have no experinec how hive developes. Even if beginner gets total hive, he may loose yield when hive swarms. It is more than easy.
My thumb rule is: don't feed after beginning if bees get nectar from nature.
