We have a young cuckoo maran (6-7 months) She appears to be ill. Her symptomsare as follows: She seems to be puffed up, doesn't make a sound, she does not have a strong appetite, has beak open most of time, unsteady on her feet, has wet poos, but not bloody. We do not want to lose her. Does this sound like anything familiar? We are keeping her in the house and away from the rest of the flock.
