Our chickens are 5 weeks old. One has been sickly for 4 days other bird were pecking at its butt. We put in a different cage. For a couple days.
Today that one died and another bird was dead too. The one the was sick had a water bubble under one of the wings. What could be happening???

There is not enough information to be able to help. Many poultry diseases can have similar symptoms. One possibility would be coccidiosis, but would require examining the dead bird to find out for sure. You might check with your local veterinarian to help you follow up on cause(s).
