Has anyone had success breeding Gouldian finches in wicker nests?
I'm currently getting one of my Gouldian pairs ready to try breeding this month, and they definitely seem eager and like they're getting into good condition. Pearly beak on the male, charcoal beak on the female, lots of displaying to each other and playing with pieces of grass and making buzzy "nesting noises" while poking around the upper cage corners.
I bought a wooden nesting box earlier this year, and I decided to put it in the cage this week to see how my Gouldian pair would react. They were wary of it at first but then got used to its presence and started to seem curious about it, especially the male. He keeps perching near it and craning his neck looking like he wants to hop in...but then he changes his mind and leaves. He has even gathered bits of grass in his beak and brought them up to where the nest is, peeking into the hole but then giving up yet again.
It seems like there is something about the nest box that my finches don't like, and I am not entirely sure what it is. This is my first time attempting to breed Gouldians, and my first time attempting to breed finches in nest boxes at all. Before this I have raised and bred shaft-tail finches for quite a few years, and they always used covered wicker nests, so that's what I am used to. But I keep reading that Gouldians prefer wooden or plastic nest boxes, and have much better breeding results when using them.
Out of curiosity, I tried putting one of my old wicker nests in the cage, and my finch couple took to it almost right away. They both made the buzzy sounds and seemed really excited about it, and both birds took turns hopping inside and rearranging the nest material I put in it.
I took the wicker nest back out for now as I am still figuring out what the best route is to take. Should I just let them give it a go in a wicker nest and see what happens? Is there something else I could try to encourage them to enter my wooden nest box? Or should I try buying a smaller nest box, perhaps one of the plastic ones with a wider entrance? (The box I currently have is a rather large one with the entry hole offset to one side.) I appreciate any input that more experienced Gouldian breeders can provide.
Update: Thanks for the input so far, everyone! I have decided that I am going to try the wooden nest box one more time in a different way. There is a panel on the short side of it that slides out, leaving a decent-sized square hole that the birds could more easily get in/out of. I am thinking that maybe they are intimidated by the small size of the current entry hole. I will seal up the smaller hole with cardboard and see how they like the bigger entrance.
If that doesn't work, I will try the wicker nest since they seemed happy to use that. And then if that doesn't give good results, I will experiment with some other types of nest boxes, like cardboard and plastic, to see what they prefer. I will keep you updated!
