When the January transfer window opened, Picken was consequently loaned out to Notts County on a one-month deal. He made his Notts County debut two days on 10 January 2009, where he made his first start and playing 90 minutes, in a 2–1 win over Exeter City. Three weeks later on 31 January 2009, Picken played against his parent club, Chesterfield, having been given permission to play against them, and lost 1–0. Shortly after, Picken's loan spell with Notts County was extended until the end of the season. He established himself in the first team at Notts County and went on to make twenty–two appearance for the club. At the end of the season, the club and Picken himself were keen for him to sign for the club on a permanent basis. However, Picken didn't sign on a permanent basis, as the club signed Brendan Moloney on loan instead.
