Strange golden capped conure behavior
So I've had my golden capped for about 15 years. I was told it was a male when I purchased it. For the past 2 weeks, the bird had been acting very, very strange. Was very cuddly and affectionate (Way more than normal, almost needed constant snuggling, wouldn't stay on its cage), was trying to find places to hide in, actually flew over to my bed and hid in the blankets. I couldn't figure it out but the bird didn't look sick, I let it go.
So 4 days ago it's acting even more strange, tail feathers are spread on top of its cage, and out pops an egg. Now, I have no experience with this, she's never laid an egg before, so off to Google I go. She looked fine, eating normally, lively, made a very strange "chuckle"? I guess you could call it noise for a few hours after laying the egg while in her happy hut. But now, 3 days later, the bird is acting strange again.
I've researched egg binding extensively and this does not appear to be it. The bird is moving around, flying, perching fine, right now is chewing on a toy in her cage.
There are two things that concern me right now:
1) Acting very erratically. After seeing the first egg I went to the pet store and bought vitamin supplements and a few cuttlebones for the cage. I scraped cuttlebone into her food every day to help with calcium intake as well. The bird is eating seed shells. Literally finding empty shells and eating them, never done this before. Is this a a birds way to get calcium?
2) There is a bulge near her vent. She doesn't seem to be straining, I tried a hot water bath but nothing happened, is this just another egg forming? I had read that generally 24-48 hours between eggs was normal, this is 72 hours now. Can there be this much time between eggs?
Sorry for the long post, there are no bird vets near me open until Monday morning and no emergency vets that I can find via google/phonebook. I'm trying to just stay calm and assess what the bird is doing and what's wrong but some input would be very helpful.
