The Novice Owner is back again ...

We have had our four hens about a week and a half now - three of them seem happy, contented, scratch around and lay the occasional egg. 

Number four though, Hettie, seems still a little withdrawn.  She follows the others round and picks at the grass, moss etc but she does tend to stand in one spot for long periods asleep.  She drinks well, takes herself off to bed at night and eats (although I don't think she has as much as the others).  I noticed too that her comb is alot more underdeveloped than the others so I am wondering if she is maybe a little younger - she certainly seems a little smaller. 

On the plus side when my husband went into the run with a bread roll and tossed it around she zoomed after it and managed to outrun some of the others!  So it isn't that she isn't eating ...

Just a little concerned and thought I'd ask what you all thought.

No definitely no sneezing or wheezing.  She is a White Sussex.  We believe her to be about 14 weeks old.

Thanks so much again for the advice!  Today she seems a bit brighter and is eating and drinking OK.  I will follow up your suggestion though about the cider vinegar and garlic though while the weather is so cold.
