Ive been reading that giving budgies (and other pet birds) egg shells is a good source of calcium. Is that true? If so, how should i give it to them? Ive read that some cook the egg and shell together and feed that to them and others that just microwave the empty shells and put those in the cage. Any suggestions on how to serve them? Also how often should i mist or place a bath in their cage? Sorry so many questions, I just want to make sure I give them proper care.
Oh, one more. Can they have watermellon? And what parts? Inside red, white, or outer part?
