Creaking runner?

[MolliMonster99]

Hey all!

So I think I may have asked this question before, but what does this weird creaking sound mean?! I finally caught a video of Frances while he was grooming and you can clearly hear the sound. However, my other runners make the same sound when they're just standing in the coop! Any ideas?

Not sure what you mean by creaking noise.

My fawn and white runner made those type noises as well - she's my only duck who ever made strange sounds - I thought it was her gizzard grinding food? She appeared to be unbothered by it!

If you watch the video you'll hear what I mean. All my runners make this noise.
