My lorikeets pooped on my cockatiels head! Is it bad?

Hi Parronts,
I have a question to ask and it may be weird but Paris pooped on Firdy's head. I'm scared that a lot of germs will be carried by feces but Firdy, you just can't touch her! I tried to grab her and smudge of the poop with water, but I think I'm stressing her out too much. Please help! So you think if a bird poops on another bird, ( especially the head) is bad?! I'm worried that something bad might happen? Because Paris's poops are watery, like a normal lorikeets poop would be.
Thanks

My birds actually do poo on each other, I think they do it on purpose , I just clean it off,,,little monsters
