Hey all, I just signed up to ask this on behalf of a relative who's recently built a coop and bought some chickens, and has been having trouble, as they sometimes just die overnight. They look and act perfectly healthy in the evening when the coop is closed, but sometimes in the morning one is just dead with no apparent signs of injury, or is about to drop dead - won't eat, drink or move, just sits there with eyes closed. What are the possible causes of this? Could it be a night-time invader? The relative seems to think it possible, as she says the coop is a mess on those mornings and the chicken is most often found exactly next to the door. Is there any chance they could be doing it to each other? Another thing, the same person has a dog kennel and has a good bit of experience with dog breeding. Her most recent litter has had some unusual problems from the get-go, and she thinks it's likely due to an infection. She's worried that it might have been transmitted from the chickens by means of dust and powder from the coop sticking to her clothes and shoes. Is that possible, and what preventative measures should be taken when handling both dogs and chickens?
