I disagree with Ziff ---- Sorry Ziff 10 different beekeepers at least 15 different answers. Some are going to change their mind before you finish asking the question
Answers below are my opinion for what it is worth:
1-I rarely rotate a brood chamber -- except when the top box is honey bound and they are not moving down. They will usually move down on their own. With that said, if you want to rotate them. When the pollen and brood starts, on a warm day switch them around- if cool just don't bust up the brood frames in the chambers.
2-If the hives are light start feeding now. If they are not light don't feed. We have had a mild winter. Just remember if you start feeding it will stimulate brood production with the pollen coming in and you will have to continue feeding if you start. If not you may increase your population of bees and if no nectar to gather they may starve.
- Feeding pollen - if none coming in only feed during our cool weather late winter and early spring. Feed very small patties or ropes (roll it up in little rools and prop between frames) are even better. Feed only what they can consume an move quickly. Pollen patties in a Southern area with SHB spell disaster.
3- That all depends on the timing for the year. As they begin to store nectar and or raising bees add a super. It will;l not hurt to add a super too early but It will hurt to super too late (swarms)
4-My opinion do away with the excluder period. Just my opinion
excluders help swarming especially with beginner beeks. Let her lay don't confine her.
5-Yes - feed until the flow starts then stop. If you feed remember to give them room and don't overfeed and cause honey bound. Not likely early in season as hive is growing. Pollen patties be aware of SHB! I can not emphasise this enough.
The bees did not draw the comb out last year, probably late in the season, after flow, because they saw no need for it. They will draw after flow only if they need it or you continued to feed at the tailing off of the flow to make them think there was still a flow. Once the flow stops and they sop drawing it is hard to induce them to do so.
Gonna skip the other Questions at this point. I peck and pick and time restraits at this time. Remember all of the above is just one beekeepers opinion
