As long as you have diligence and a good enough reward sure you can train her.
You have to be nearly OCD to be sucessful.
You'll need to put your rewards in a container, never change the container it is your chicken whistle.
Start easy call her name throw a treat immediately, let her see where it came from.
Do this at a set time everyday, as many times as you want.
Eventually you'll call her name and she'll come to you.
If you want to finger train her, wait until she's on the roost give her a treat.
Put one finger under her toes, lightly lift until she steps onto your hand.
Show her a treat, don't let her have it just yet.
Rub her toes, give nice little pets, have her hang out a while.
Put her back on the roost and give the treat.
You"ll have a finger buddy in no time.
It is just repetition and reward.
