Thank you. He is actually a new flock member only been in the flock for about 3 months no one else is sick though. But about 4 months ago they had a bacterial eye infection that about 2 or 3 hens had.

It sounds like he might have caught what your other chickens have had. Most respiratory diseases, such as MG, make the whole flock carriers for life. The disease will affect any new members of the flock until the last chicken is alive. Close your flock. Testing would identify the disease, so you would know if antibiotics would help.
