we have 8 birds,two are african greys,they are 10 years old, today when we went out to get them and bring them in,they had an egg in an old wooden box up on the wall,we aren't really sure what to do about this.Will they have more eggs,will we have to take the egg, do they know what they are doing,should we leave them alone,do we need to separate them from the others,why has this not happened before? Any and all advice would be appreciated. thanks Christy:unsure:
