Hello everyone. We received our new chicks on Wednesday of this week and today as we cleaned out the brooder and were checking the chicks over we noticed that one chick had quite the build up of poo on her rear (more than any other chick and really not right) we cleaned the area with a mild children's soap and warm water in a bath and were able to get the area pretty clean, dried her off and put her back with the rest. now late at night she has been the only one up peeping and is quite lethargic only takes a step or two and continues to peep. she has not really eaten or drank any water that we have seen. does this seem to be a digestive issue or something else we should be looking at?
