I have a chicken who seems a little off, she walks around for a bit and then stands still for long periods of time and at time just nestles her head into her wing. She's not acting normal (she's normally running around up to no good with her twin) Two days ago, (probably yesterday aswell) and just now she's laid eggs with no shell. They come out as a sack and the egg white and yolk separate. She gets the same diet as all the other chickens, and extra grit is always available for them aswell. Yesterday we had huge rains and it flooded the chicken run, thats about the only thing thats been different lately. The water has subsided now, and they've been busy eating all the worms and snails thats about. I have her inside right now to keep warm and feed her some bread as she didnt want to eat scratch mix or pellets today Anyone have any idea what might be wrong, or what i could give her to make her feel better? Or something extra to give her other than grit to help her make proper eggs? Is this a case where I should give apple cider vinegar if she has an upset tummy? (i've yet to buy some..but can get it from my work) or does it sound like she might need some antibiotics? Also some sort of calcium supplement? Thanks in advance!
