I returned late Tuesday night from my trip to find both birds seemingly very healthy, active and rather normal. Except the hen was uncharacteristically quiet, docile and passive.

Wednesday both birds spent most of the day frantically searching their cage for a nesting spot -- still ignoring the nestbox (of course). But on Thursday morning I noticed some odd behaviors in both birds that I'd never seen before. The male tried to mount the hen immediately after their usual courtship dance, and was on her for a second or two. I don't know if he succeeded, or if it was his first time....but it was the first time I'd seen it. For the rest of the day yesterday, and continuing today, the hen has been acting quite strangely -- beyond the sudden passivity she adopted while I was away:
- 1) She sits much of the day in a quiet upper corner of the cage, often shutting her eyes partially for a moment or two, as if she's struggling to keep them open. She's not usually one to nap during the day, unless it's near roosting time.
2) She occasionally puffs-out her feathers for a few seconds as if she's preparing to poop, but usually nothing comes out. (But she sometimes releases droppings that appear fairly normal in size and color, so I don't believe she's constipated.) A few times I've noticed her with a wide stance during these puff-outs.
3) She occasionally will also suddenly lean forward with her beak open and "freeze" in that position for anywhere from a minute or two to as long as 15-20 minutes. I've noticed this several times yesterday, and again today. During these episodes she has a very menacing look. I don't know if she's in pain or exactly what is happening, but she seems in distress of some sort when this happens.
She has been receiving calcium drops in her water for the past couple of weeks, and she also has 24/7 access to cuttlebone, eggshell and oyster shell. I've seen her regularly nibbling on the eggshell/oyster shell grit mixture, but not on the cuttlebone in several weeks. But I really believe she's receiving enough calcium.
I'm not sure the same is true of protein. Her appetite is perfectly normal -- she's eating as much as she ever does. But she hasn't had access to the usual eggfood for the past couple of weeks while I was away. She has been nibbling heartily on the Miracle Meal I added yesterday, and tomorrow I plan to resume their eggfood.
Yesterday I added some Morning Bird "Thrive" to their seed, along with some of Rob Marshall's "ER Formula" to help boost her immune system. She does seem to have perked-up a bit today, compared with yesterday. But she's still not behaving normally at all. Today I returned their heated perch to the cage, which I had removed in the spring....but she hasn't been on it yet. They both know to use this heated perch while preening after their baths, so I'm hoping if she needs the heat, she'll find her way to it.
Do any of these symptoms seem to indicate eggbinding, or possibly an illness? Or is she maybe just traumatized from his attempt(s) to mount her? Maybe she developed an infection from only having their water changed every other day while I was away (despite the addition of apple-cider vinegar to their water)? Do either a hospital cage or vet visit seem necessary at this point, or would that stress her out even further?
