After a heavy rain with dropping temperature I had a silkie hen get bubbly eyes. I guess the wind blew the cold rain into their pen. It's the time of year for chicken viruses and bacteria...just like humans.
I brought her in the house for 2 days, started her on sulmet (I've GOT to get some water soluable Tylan this week). She's eating and drinking ok. I also started the entire pen of silkies that she came out of on the sulmet as well. I also put terramycin in her eyes each day. If you catch it early enough she should be fine!
