your cockatiel egg has poop on becuase the mother bird needs to incuabate it and birds are not like humans where they are going to go in a particular place to use the washroom and btw thats normal
Upload a photo of it here. Don't touch it that's normal, nothing will happen
Just wash it off.
For heaven's sake, get a grip on yourself. It's no big deal.
Wrap it around ur beef bayonet
Please please answer! I don't know what to do!
