Yes all excellent advice! I may be scarred from raising chicks after this.

Honestly if I’d have been more prepared I would have done all of this. I wasn’t really sure I was going to leave her to sit until it was too late to do all this. It was one of those back and forth things like - no we don’t need to raise more chicks, we have enough on our plate - but then curiosity took over once she continued to sit so diligently. I will definitely take all this advice on board if there is a next time.
She seems to have sorted her one leg out and is attempting to walk now at 6am. She still looks very wet and seems weak and sleepy, but she is chirping and trying to walk/pushing herself around and definitely fights and chirps when I picked her up to show her the water.
When I placed her beak in the water she did take a little gulp but then kept holding her head back and opening her mouth like she was still gulping and I was worried for a second she was drowning or maybe couldn’t swallow. Is this something they need to learn at hours old or does she maybe have a problem there? Again, these most basic things have always been taught here by a mother hen. I am completely clueless here.
Thank you all again so much for your responses. Nearly 24 hours in and I can’t believe she’s still alive. Im really rooting for her but just don’t know yet how this will end. All suggestions are appreciated. I will stop and buy some vitamins this morning for her. When do you know if you need to syringe feed?
