Thank you for your question. We reached out to the manufacturer and here's their response:
In my experience with different situations and conversations with customers, it seems that some birds never will get used to certain accessories, toys, etc. I have been told often that time is the best indicator of whether or not a bird will ever get used to a cage, a toy, etc. I've never been told an exact time frame but just my general opinion would be to give it 4-6 weeks to see if the bird will give it a chance and if not, take it out and go back to the one they know & prefer. However, if they are trying to get the birds to mate/reproduce, that may be too long of a time frame and then you lose that opportunity because I think right now is mating season. So if that's the case, if they are trying to get them to mate, they should probably try something else that the birds are more comfortable with.
