Hello, my silkie hen who is 4 years old seems bloated and possibly spraddled her legs (or it's just added weight). I was gone on a 2wk vacation and had family and friends watch my chickens. When I checked on my silkie she had trouble getting up this morning and she still does. When she attempts to walk she falls over. Also, she did have a good amount of poo stuck on her bum however i did take it off easily, it crumbled right off. I added electrolytes to her water, but I'm not sure what is really wrong with her. Can someone please help guess what may have caused this and what this is? Thank You.
