even though you got a swarm, make sure the queen is in there. sometimes a swarm can contain 3 queens, or none. feed sugar water for awhile ,until they get established. the proportion is; 1 cup water, 1 cup sugar, you need a "board" to sit the perforated lid jar on. heat the mixture, do not boil, 190 deg.cool down.
way to go, I've caught swarms this Spring, my buddy, P'nut, in the Smokies has caught over 61 this Spring, TN Mutt Bees.
Talk to your local Bee Keeper Association for supplies and first hand knowledge.
A new swarm will out work an old established hive, 2 to 1
