Sick chick

[luvpets2016]

Hi,

My problem is : yellow diarrhea,not eating, waddle has flopped and down. Been this way for a week. She is separate from others. Shes a Isa brown ,age unknown, 1 of 11 chicks.She is laying eggs and I have had her and her sisters (5 MORE) at least 6 months.
I have tried : scrambles eggs, yogurt, diced fesh fruit, vinegar and No improvement so I just put on Sulfadimethoxine, but after reading all about it I pulled it after 1 day usage b/c shes older than 16 wks and is a egg laying .
But now what do I do ????
She just seems to be doing just as bad.

Shes normally enclosed in a electric fence areas about 300 sq ft,with 10 other chicks who are fine. On dumor flock b/c I have a turkey who is my rooster for my flock (Been with me for 5 years ). Yes ,I know deseases can be transmitted. But he's fine and been with the rest of the life long chicks They get some treats in am and maybe some fresh fruit and vegs.

Any other suggestions?
Thanks

Any pictures of her and the poo?
Has she been wormed?
Can she stand, if so does she stand hunched up, normal, like a penguin, etc.?
When was the last time she laid an egg?
Separating was a good idea. Hydration is important so encourage drinking, you can add some vitamins/electrolytes to her water if you like.
