This is going to sound really stupid and probably aggravating...
I totally hear what you are saying. I have read everywhere that you just shouldn't give them a nest. I know this fully and yet despite all this I am still ignoring all the expert advice for some reason... Sounds really stupid I know... Don't give them a nest. I gave them a nest. Don't give them nesting material. I gave them nesting material, etc. I brought this on myself and knew full well what would happen in the end. I can't really justify my reasons because they are silly and again, go completely against tested, proven, veteran, expert advice. Part of me wants to breed them at least once. Part of me wants to just experience the process once to observe their behavior during this time (In some ways, this whole experience is still an experiment for me too as I slowly get into birds and understand their behavior), part of me just thinks they are so cute in their little coconut nest, part of me hates the idea of taking that away from them even though I know you are 100% correct that they will be fine. I guess in the end, I was hoping that I could help control it with the dummy eggs, or that their breeding frequency would be such that it would be manageable. Perhaps I am being selfish and not thinking about their well being. I guess the other part of my logic (er... faulty logic) was that it was inevitable. I have read numerous times that they will nest and breed regardless, even to the extreme of just laying eggs on cage floor. Cant stop nature. So I guess my thought process was, well since I am stuck with a male and female, and since its going to happen anyways, I guess I will just give them something cozy and safe to nest in instead of on the cage floor. Again I realize that this is all probably pretty faulty logic and that I am probably just being selfish. This is why I went ahead and prepared to separate them with the new cage. I have not brought myself to do it yet, or to remove the nest yet, and part of me still just wants to go through this first cycle anyways for the experience. I have learned a lot actually just in these last few days. Complete change of behavior in both of them. It's exciting to see something completely new. I will go on to say that I feel I have prepped as much as I can. They have a cuttle bone a mineral block in the cage. I am providing egg food as well as fresh hard boiled eggs with the shells. I'm prepared to take them to the vet if necessary (egg binding or something else). I have dummy eggs in the mail. I have also been doing extensive reading on the ins and outs on breeding so I am ready when I do decide to actually hand raise my first clutch. I look forward to all the backlash from this post haha.
