Most babies don't like sleeping in a crib so this is pretty common. Cribs are big, empty and not exactly comfortable for a baby.
IME it just takes time for them to get used to it. Both of my kids were swaddled when I started putting them in the crib, and they stayed in the crib as I transitioned them out of the swaddle. It just took consistency and time.
