Hen falls forward and to one side

[Lorli]

My little Serama hen was fine until yesterday, when she was sitting on the ground by herself while the others were eating and walking around. When I put her on the grass, she tries to walk and she falls forward and then onto her left side. I brought her in the house last night, in a box, and she is the same today. The big hens were pecking her so she is back inside now. One of them knocked her onto her side and she couldn't get back up.
She is eating and drinking and her crop was full last night.. I saw poop yesterday and it was light brown and wet. I don't see any signs of trauma. Her legs seem strong and they move freely but she keeps the left one tucked up more than the right

I tried to get a video of her walking but she sat down in the sun and didn't get up. These vids are the best I have.

I appreciate any advice, she's such a sweet little thing (like a crow except smaller).

Could the one leg she is holding be broken?

Could the one leg she is holding be broken?

Hi, thanks for the message. I didn’t think it was broken, at least not enough for me to see. She passed away after a week and I’m so worried about the others. I’ve been watching them closely and they’ve been ok so far.
