Diana, I read your questions and yes, I think she is definitely trying to nest. After two years of being together, mostly in the same cage, Milly did the same thing, starting in early January. She laid 16 eggs between January and March (a very stressful thing for her little body). Every time, even after I bought the nest, she abandoned the little eggs, which were fertile, we found. (Thank you, Roger, the "stud muffin" ). I had to separate them (their cages are side by side), but when she laid that first clutch, I let them remain together, and he would sit on the eggs, in the nest, when she was out to eat and drink.

I have researched and researched and I will try to find you some of the helpful articles I read that helped me.

Milly is now sitting on 3 new eggs, so we have started the whole thing over again! I had removed the eggs and the nest after she laid that first clutch and abandoned them, but she is diligently sitting, right now (almost a week now).

Make sure you give her plenty of things with calcium. The cuttle bone is a good start. Fresh veggies, pellets, etc are good sources as well.

I had no plans to breed and they never gave me any reason to worry, then "bang", I had the same thing going on that you do!

Don't hesitate to PM me or email. I am no expert, but I know where those experts are now!!!
