Budgie breeding tips, healthier chicks.?

Tips to have healthier chicks is to keep the cage and the breeding box warm at all times. also recommended that u keep them inside in winter( as it is here) and cover them up every night. also remember that it is important to make sure that the female is pregnant, since the budgie could die if u force her to go into the breeding box. keep some warm things in the box and keep the temperature a little over medium temperature near the cage. good food and vegetables would include carrot ( wat i fed to them) and other things that are fresh, clean and not to cold.
