If you see that the belly of the female parrot is obviously larger than before, the tail is droopy, the feces is larger than usual, and the male bird vomits food to the female bird, it basically means that the back stepping is successful.
If a breeding box has been prepared, they will frequently go in and out of the breeding box, and even pluck their own feathers to bedding. These are also signs of successful back stepping. If this happens, the owner should try not to disturb them and provide them with a relatively quiet environment to ensure smooth production.
