I strongly suggest that you put blinders/peepers on your rooster.
As far as your EE is concerned, I dont know if the eye closure is due to an injury from the rooster or if it's due to the respiratory infection running through your birds.
Personally, I'd rather deal with an eye injury than a respiratory disease.
The treatment for the possible eye injury would be to flush the eye with saline solution, gently pat dry and apply a tiny amount of Terramycin eye ointment in her eye twice a day as needed until healed. Neosporin can be used if the Terramycin is unavailable.
If it's due to a respiratory disease such as MG, follow the same procedure as above but also give your sick EE either Tylan 50 or Baytril. Give your other sick birds either medication as well. Only time will heal your EE's cheek.
