HELP FOR SICK CHICKS

I bought six Buff Orpington pullets two weeks ago from a local breeder. On Wednesday I came home to find two with eyes swollen and matted shut. I got warm water and clean rags and wiped matting off their eyes. One chick was significantly worse than the other. Hard white pus came out of each eye with a large almost dime sized out of the right eye. I also noticed that they kept opening and closing their beak although there was no coughing or gasping for breath. I cleaned the eyes out again yesterday morning and both girls are able to partially open their eyes, although they preferred to keep them shut. And I started them last night on Oxytetracycline and eye drops v.....,,? I added electrolytes to water this morning too. They do shiver as if cold and stay under heat lamp so I put their food and water in their house close by. Really sick one is hanging in there and will drink if I put her in front of the water and dip her beak so she knows it's there. She will drink and does stop when she's through. She ate some vanilla Greek yogurt last night and this morning. The rest are eating and drinking OK but are beginning to exhibit symptoms like the two sick ones. Any ideas of what this could be? And am I treating correctly? I love my girls and don't want to lose them. They are in a coop by themselves.
