these are my got o signs of a broody hen:
Is she on nest most the day and all night?
When you pull her out of nest and put her on the ground, does she flatten right back out into a fluffy screeching pancake?
Does she walk around making a low cluckcluckcluckcluckcluck(ticking bomb) sound on her...
Vids have to be uploaded to YouTube, or similar platform, then linked here.
Pics are fine if they show what we need to see, which is the whole coop and run.
