I went out to feed this morning and heard the weirdest sound coming from my hens. If you're over 40, remember the sound the baby dolls made when you flipped them over to cry? That's the sounds they were making. I put terramycin antibiotic powder in their water and kept them confined in their coop today. Am hoping I don't come home to a bunch of dead birds I'm really kicking myself in the head HARD. I rescued 3 hens last week. A couple of them were sneezing but seemed ok. I had them confined to a rabbit hutch but there just wasn't enough room. I STUPIDLY moved them to the dog pen and confined them there, but apparently it wasn't confined enough. You tried to tell me; I didn't listen. Other than the terramycin, what else can I do for them?
