If you lift her head and support her neck can she eat/drink on her own?Okay, I will read up on this.
Never culled a chicken before- is there a kind way to do this?
I will give her some time before we do that though. Giving her lots of vitamins and water. She ate some today but not very much.
You may need to syringe or tube fluids into her, but you'll have to manipulate her neck up a bit to do that.
As for putting down a hen that's in misery, I use the broomstick method (cervical dislocation). Others will hopefully chime in with their thoughts.
