my friend found a quaker by her pool area in orlando fl, i took it over from here, and noticed he's been plucked or have been plucking himself., any suggestions on what i should do?

First, I hope you are trying to reunite this Quaker with his/her owner.
While trying to determine proper ownership, provide him (I'll use male pronouns) with a healthy diet and observe if he is plucking his own feathers. If after a reasonable time, you are unable to find the owner and choose to keep him, bring him in for an examination by an avian vet.
Good luck with helping this Quaker.
