Welcome to the forum, Les!
I'm in North-Central MA, so I'm still battling the cold, too. Last year was, for all intents and purposes, my first year. My bees didn't come until Memorial Day weekend, WAY later than they were supposed to.
Anyway, I would agree with keeping the draft out and avoid using a screened bottom board.
More experienced cold-weather beeks will hopefully chime in on this, but I immediately had a few thoughts about feeding:
1) Are you using all new foundation?
2) With the current temperatures, I'm not sure they'll take the cold syrup. Maybe have two feeding jars (and top-feed, with a hive-body around it). Keep one jar inside over night and swap them each morning. If the syrup is too cold, they won't take it.
3) I would recommend feeding 2:1 until all your foundation is drawn. Using 1:1 syrup will force them to have to dehydrate it that much more. One of the beeks on here had said they ONLY feed 2:1. I think I'm going to always do the same, but I may do some testing on that as my apiaries expand. I started with 3 hives last year, but due to queen issues, I had to combine one into the other two as we headed into winter. I hope to split and may catch swarms this year.
Good luck!
