Hi, I am a new member but have been a BYC user for a year. I have not been able to find any great answers on this after searching for a week off and on. My Plymouth Barred Rock Hen, Zeebra. (a little over a year old) She became under the weather back in July on a really hot day (for here in the PNW). I treated her with electrolites and cool water, shade and fed her oregon grapes (mahonia berries). Besides the birds loving them, they are supposed to carry antibiotic properties. She healed up in 24 hours with a full recovery in 48hours. But, she continued having watery poop. Just like the one seen in this link http://chat.allotment.org.uk/index.php?topic=17568.0 Understandable because is IS summer after-all. But, she began laying "shelless" eggs. She has been laying these shelless eggs since then. Over the past 3 weeks or so, I have noticed the eggs gaining shell. By now, they are almost hard enough not to break when layed but still remain very thin. She is still pooing watery poo all the time. The weather has been considerably cooler for the past few weeks - down into the 50s at night and the 60's in the day. She also seems to have lost quite a bit of weight. She is now the lightest hen of my 4 when she used to be either 2nd or 3rd heaviest. Here is the kicker... ... she has no other problems. No drainage or sneezing, no lethargy etc... She eats like a monster (this is her usual) and drinks. She runs around, catches bugs in the air, is bright eyed and "bushy tailed" (feathers are kept and she preens regularly). Is this something I should be concerned about? Additional - the flock just finished a round of antibiotics per Vets' suggestion while I treated half the flock for bumblefoot. I will be starting them on probiotics today for thier post-antibiotic recovery. Other than the 2 others that are recovering from the bumblefoot, they are all in good health. I try to worm once a year (usually in the winter when egg production is down and the weather is wet and primed for worms here). Have not wormed yet this year. Poop had NO blood and I can not see any worms. Like I said it is textbook watery - just like the pic in the link.
