We just got our first hen from what turns out was a very dodgy flock owner. We've had Peggy, a 6-month old Australorp/Barnevelder mix, for about a week and a half. She's our only current chook, seeing as we've discovered that she's got both lice and coryza and decided to postpone creating a flock until she's healthy. So far we've had a vet check her out and, after discovering the lice/early stages of coryza, we've been subjecting her to the lice powder weekly and Lincospectin Solu Powder daily in her water. She's still itching (understandable, she's due another lice repellent dusting in the morning), occasionally plucking feathers (...lice? Or lack of company? Or something else??) and while she's still coughing and throaty-voiced, she hasn't got any more bubbly eyes and is definitely improving. She normally likes to chat with whoever goes up to her and will eat out of our hands, though she doesn't like to be touched yet. Which is where we start to worry. I noticed she made next to no noise last night and hasn't tonight either (her coop is not far from my bedroom window and I normally hear her cluck a few times during the night. Not sure if that's normal for a chicken). Yesterday morning we noticed she didn't call us out at all (we try to let her out at 7-7:30am to roam the yard, and she usually starts calling us around that time). She did cluck a bit when I went out to see her, but for the rest of the day was oddly quiet. She didn't even cluck when a neighbour came over to say hi. Weirder still, when we let her out again in the afternoon she was fairly quick to return to the coop. Mum found her standing on the roof of the coop and was able to pick her up and pet her. No fuss, no noise, no struggle. Peggy's a pretty mellow girl in general, but this level of complacency is new and sudden. She still eats and drinks okay and seemed fine when we checked on her tonight. But seeing as she's already got health problems we're a little paranoid. Other Background Info: We've got her settled in a coop (not overly big but designed to house 2 chickens. We intend to get 3, and will upgrade then) but the run's still a work in progress. So far we've been letting her run around the backyard, under supervision, for a few hours at a time, at least once a day. She's gotten into the routine and while always happy/impatient to be let out (which is why her sudden fondness for the coop worries us), is also good at returning back to the coop on her own. We feed her grit, pellets and veggie/fruit scraps and let her peck around the grassy yard. Since it's been rainy the last few days she's been finding a lot of worms, but we try to make sure she's inside the dry coop as soon as it rains/if the grass is too soggy. Her coop has alfalfa in the corner and more in a laying box, though she doesn't go into the latter and hasn't laid any eggs yet. She's only 6-months old and still new to our home so we haven't questioned that, but should we? She also has irregular droppings; sometimes firm and other times really runny/watery. Yesterday morning there was basically a small puddle. Does anyone have any idea what's wrong with her, or if we're overreacting? As I said, she already has lice and coryza, so it might come down to that, but I'm still unsure.
