On departure between 5;000 feet and 6;000 feet; multiple bird strikes on the aircraft. Felt like the majority of the strikes were on the right side of the aircraft and there seemed to be a vibration coming from the airframe and/or engine. Engine parameters were normal and within limits. The vibration indicator on the #2 engine was a little higher than the #1 engine but again everything was within limits. We started a descent and right turn to return to ZZZ. An ILS was flown were an uneventful overweight landing was accomplished. Airport fire and rescue scanned the aircraft and we taxied to gate. During taxi; the #2 engine was shut down to a noticeable vibration when power was advanced from idle. After parking at the gate; maintenance looked over the aircraft and advised us that there was a hole in the lower right radome; damage to the fan blades on the #2 engine; and multiple impacts on the right wing and winglet. Dispatch was called after parking at the gate.
There was no abnormal engine indications but; there was a loud vibration sound.
An air carrier crew departed and struck a bird flock between 5;000 feet and 6;000 feet. Because of engine and airframe vibration the crew returned to departure airport where damage was found to the radome; #2 engine fan blades; the right wing and winglet.
