Last night I noticed that one of my 6-month-old Red Sex-Link pullets was wheezing when she breathed, with a real gurgle-y liquid sound in her sinuses. None of her coop-mates sounded anything like that. I couldn't find the bottle of Vet Rx so I slathered Vicks Vap-O-Rub on her wattles & comb & dabbed some under her wings. When I went to put her in the hospital pen she had some difficulty grabbing onto the perch, which concerned me. But after several tries I finally got her to grab on to it. This morning there were lots of small, dark/almost-black poops each streaked with white under the perch. The white is the typical stuff you find in poop, I forget what it's called but it's the chicken version of urine. But the poops were small & thin, like what you find under a rooster, not the plump pullet poops. And dark. They've been eating layer pellets, and fresh pumpkin, and get to free-range each afternoon. She was eager to eat the dish of layer pellets I gave her this morning, & she's walking & clutching her perch just fine. Her breathing sounds much better too, but when you put your ear to her chest you can still hear a wheeze in her lungs. I'd like to hear any advice you have as to what I can do to remedy this ailment & relieve her symptoms. There is someone who wants to buy her & 3 more of her flockmates and I want to sell her healthy birds. Thank you for your imput!
