Prior to, Ancona Chicken was sold by Magus Tirth at the Mirage Raceway in Thousand Needles for. Now it is sold by "Plucky" Johnson, a chicken that runs about in Tirth's Haunt. When you manage to catch up with it, he will turn into a man and offer the chicken for sale. Alternatively, killing Mad Magus Tirth will turn the chicken into the vendor NPC.
