Hen's Eye with Pus

[Zarzoor]

Hi! I have 4 young hens (about 3 months old) and my sisters noticed the other day that one of them had a reddish pimple near her eye. I was chilling with them today and her eyes had like a whitish pus/bubbly thing? I'll insert a picture. She's acting normally and eating like normal. Only weird thing I noticed is that her voice is much louder and deeper if that makes sense? Please help! She's a Blue Astrolop

She looks as though she has nasal drainage and a dripping from her beak, as well as the bubbly pus-filled eye. That might be signs of a respiratory disease. I would,clean the nostrils and eye by flushing a little saline into the eye twice a day. Then apply some Terramycin eye ointment into the eye twice a day. An oral antibiotic such as Tylosin powder given in the water may also treat it. Does she have a bad odor in her face? Is she sneezing or is her breathing rattly?
