Hello everyone

I have been reading alot on this site. I have purchase a package last year and it was so dry and I was wondered if they have enought honey to last through winter and the winter here (Utah) was so cold this year, I thought they probably all dead, but to my surprise last saturday the temper hit 50 F the first time and I saw my bee coming out. I was so excite that they made it. Since this is the only hive I have and I will be going to split them, but still don't know how to split them. Should I do a walk away split or buy another queen. Any advice is greatly appreciate.
