What do you need to do for a parrotlet to step on its back?

Notice to look for some hay cut into lengths of about 8 centimeters and throw it inside the cage, they will take it back to the nest and lay it on the cage during breeding, the cage should not be moved, the best way is to keep it in place, but be careful not to expose it to the sun, depending on the situation, you can give a shield to block the sun, you need to feed the hard boiled egg shells, food and sesame seeds, don't know about the sesame seeds, melons can be used as a substitute, and after the eggs are laid, remember one thing ！！！！ That is not to be alarmed, do not observe many friends because of curiosity to observe, resulting in the abandonment of the nest, the heat of the day to provide a place to bathe I hope to help Temperature is not a big problem, ventilation is necessary
