What ScottP recommended is what I would recommend for starters. You could also look at Hen Neck. Both would be around $5 and would serve you well. The Hen Neck will give you a little longer feather than Hen Back and the added length can be used for mini buggers on size 14 streamer hooks. If you are going to Hobby Lobby for supplies, you can look in the plastic flower area and you will find Pheasant Tail feathers, Ostrich Herl tail feathers and Peacock tail feathers and all of these are good supplies to have on hand for other fly patterns.
