Hi, We have four quail; two breeding pairs kept in an outdoor aviary with a few other budgies. They've been out since early September, so have had time to acclimatise. All are okay with the change to the miserable British weather as they've been bred in aviaries. Howevever we have noticed within a week (clean out once a week) that a male quail has lost a lot of weight so much so that the breast bone and neck are clearly visible, there is no picking on or fighting from any other birds. Upon closer inspection and brining him inside for isolation; he has lost feathers on all of his underside, initially we thought due to contact with the ground, but he appears to have what smells like half digested food caking the skin where his feathers should be along his front. All birds have been wormed and mite sprayed recently with shelter, wood chippings, hay and sand baths. We have mite sprayed him again and rewormed him as he's now on his own, he als has multivitamin drops in his food to give him a boost; he's eating an drinking fine, infact was drinking a lot. After two days indoors and in isolation (today) he has a completely wet front, not drinking much and keeps reversing into things. Any help or advice as what to do next would be much appreciated. Our local vets are not specialists in birds and we are not sure the quail would survive an hour and a half trip to the specialist one. I have kept lots of chickens before and never had any problems, this is a new house and new aviary anyway. Have checked the aviary and other birds for signs of infestation or related problems; all are healthy, plump, full plumage and active. Just for information; all quail are this years stock (June), the females haven't started egg laying yet as days are short. They are all properly fed and watered; quails have their own feeder and water to the budgies so have fresh food.
