Finch bird is sitting in the food and sometime he’ll get down in the bottom of the cage
He may just be wanting to nest, but if he is alone, he doesn’t need a nest. A nest triggers breeding behavior and hormones, so there is no need to stir that up in him if he doesn’t have a mate. But is he is sitting fluffed up and being inactive, he could be sick, and in that case he needs to be taken to an avian Vet.
Thank you for asking Lafeber,
