Is my chicken coughing??

[vymichelle]

I have 3 chooks, a hen and her chicks that was probably about 15 weeks old now. I've noticed one of them make a noise like a single 'buck' noise and it's worrying me that it sounds like a cough or sneeze. I've heard her do it 3 or 4 times over the last two days, so it's nothing serious, YET! They still chatter away in chick noises and I'm not sure if she's just practicing 'grown up' noises? Can anyone describe what a chicken cough/sneeze sounds like, or if it sounds normal to be just learning hen noises, or perhaps a link to a video of a coughing chicken noise?? Will look on youtube when I get a second, you can usually find random things like that on there!
Also, if it's a bad noise, what do I do to make her better?
Many thanks

My rooster did that after he ate.
I found out it was because he was eating to fast, he was getting picked on when he ate. so the poor guy would eat as fast as he could and then run away. make sure shes not getting picked on.
