I wasnt worried before but now I am a bit worried about one of our white chickens, Hettie, she has now plucked out about an inch square's worth of feathers around her bum (the ones which were messy) and seems to have a bit of a slimy discharge. She seems perfectly healthy otherwise, she's running around fine (took me ages to catch her!) and is eating and drinking well, in fact I'd say she is now the biggest of the bunch (we have 6). I'm pretty sure she is not laying yet (we're getting 4 eggs a day most days) and she still hasnt ventured out the pop hole (3 are going out and 3 staying in so far). She doesnt seem to be scratching herself and I didnt see any sign of mites or lice. What do you think, is it worms? Unfortunately it is Bastille Day today so I wont be able to get anything till tomorrow.
