I hope you figure out her problem soon. It's very upsetting when they aren't well.
As a warning to others - but ending with a smile ... I have just gone through a rough patch with some of my pekin roos. My oldest one - daddy to many of my other ones - looked miserable recently, I immediately isolated him and gave him lots of cuddles and attention but he stopped eating and died. I couldn't figure out why but he occasionally sneezed, ever since buying him last year. No sickness that I knew of, though. Then last week my beautiful Chickadee and another roo (not related) both started sneezing so I immediately removed them from the pen and brought them into the courtyard at the back of the house. They looked miserable - heads down, eyes closed, not eating or drinking. Two more roos sneezed so they were put in different cages. Took the worst two, including Chickadee who had a terrible rattle in his chest, to the vet on Monday. Chickadee's temperature was off the scale so he got an anti-inflammatory shot and I bought antibiotic powder to go in their water. As per vet's instructions I brought all the birds together into the one 2-storey coop and brought it right near the back door so that I could watch them. I dosed all water containers for the other pens although no other birds have shown any symptoms. I was starting to think that I was going to lose my favourites but I managed to dip Chickadee and Billy's beaks into the treated water and they drank like it was going out of style. I felt they were on the improve, even if only a little. I was delighted to see this morning that when we opened the door to their roosting area Chickadee was the first one out. Eyes were open, still wheezing but not battling for breath and he started eating as though he'd been on a starvation diet for weeks! He devoured heaps of chick starter which I had also put a supplement into, and some paw paw and lettuce (his favourite). Billy is still off colour, but has started eating a bit and drinking. He spent most of the day with head tucked back, fast asleep, but when awake is more alert. Only one of the others is still sneezing now so it appears that the antibiotic is working.
I feel as though I can stop worrying now and I hope that you are smiling soon, too, SilkieChickStar. Cheers Rosemary
