I at first was thinking he might have had a mild heat stroke but idk bc it's shaded and nothing else in the same pen are having any problems

Let share this research on Marek's Disease.
Symptoms: One wing hangs down or limps on one leg or eye turns gray or dries up and is just skin and bone before death. Birds 6 to 9 months old-enlarged, red feather follicles or white bumps on skin that form a brown crusty scab; lack of coordination, pale skin, wing or leg paralysis (one leg points forward & the other points back under the body), rapid weight loss, coma, death due to trampling or inability to get to feed and water; in breeds having reddish bay eyes-cloudy, grayish dilated pupil. Clinical signs "gray eye" caused by tumors in the pupils and blindness, tumors of the liver, kidneys spleen, gonads, pancreas, lungs, muscles and skin. Birds develop tumors, emaciation and death. Diagnosis is based on history of
no vaccination, presence of typical tumor pattern and affected birds. Affects chickens 2 to 16 weeks of age, stresses from other disease increase severity of MD. Herpes virus is cell associated and shed in skin scales and feather dander. Birds remain viremic for life but infected carriers may or may not be clinically ill. Vaccination protects against tumor formation but not against MD infection. Occurrence is world wide wherever poultry is produced. Transmission is primarily by air within the poultry house, in feather dander, chicken house dust, feces and saliva. Infected birds carry virus in blood for life and are a source of infection to susceptible birds. Transmission by egg is of no significance.
Possible Disease: Marek’s Disease, Incubation 14 days, Duration chronic in flocks.
Treatment: No treatment. Birds must be vaccinated at one day of age. Marek's disease is a herpes virus-induced neoplastic disease of chickens characterized by tumor formations in nerve, organ muscle and epithelial tissue with pleomorphic lymphoid cells. There is no treatment. Prevention is by vaccination, but vaccination only prevents tumor formation, not MD infection. All Marek's disease vaccine must include HVT.
Good Luck
