Chicken is Small and Smells Like Poop

[nannanc]

I have six pullets who are 4 months old. One of them reeks of chicken poo when I hold her. Her vent looks normal and her butt fluff is clean. The rest of my girls smell fine.
I've also noticed she isn't growing as much as my other girls. She acts fine and eats and drinks normally. She does tend to keep to herself, but I've never seen her being picked on. Maybe they don't want her close since she stinks Haha, but really, is this normal? What could be causing it?

Get and give her some poly vi sol..... (without IRON)
add some vinegar to the drinking water....
No I wouldn't say that smell its normal...
Is it possible she has coccidiosis...? If so get some corrid, and treat all the chicks...
Check her crop and make sure its digesting or whatever they call that for chickens.
Check in the morning to make sure the crop is empty and not holding onto the food...
I hope you can figure out whats going on... =)
