These chickens are hard to get. You need at least 60-70 narcotics just to be sure. I have 2 now because I had a farm with narc berries. And I have a lot of meat eaters to collect meat for spoiled meat. Just make sure when you go looking for theses dinos take a Dino that can hold a lot of stuff like a rex, allosaurus, carno, or raptor. These birds only take mejoberrys, vegetables and seeds that you have to make for them.
