Sometimes they just get a little limp that will go away. First you did the right thing checking him for obvious injury. Check the joints for swelling too. Couple quick questions: Does he still Roost at night and is that foot on the roost or held next to the body. If it is on the roost with the foot resting on the roost, however gently, it is a decent sign. Do you have another male in the pen also? They could have sparred a little and he may be temporarily resting a sore foot. Keep an eye on him to monitor it over the next couple days. No wrap, no meds unless you find the root cause. Have dealt with limping peafowl that had no obvious injury and they have resolved themselves.
