I recently (6 days ago) purchased a Severe Macaw. He was thin the day I took him home, but I really didn't realize how thin. He weighed 322 grams at the vet today, and you can seriously feel every bone in his body. He was on one handfeeding a day. He was hatched 8/21/06. He picks at pellets and seeds and so forth, but really doesn't seem to ingest them. He seems to drop most everything. He was eating his one time a day formula well, up to about 80cc's with the breeder. I read that 80 is an awful lot in one sitting, so I split it up into two. He was fine with the intake (ranging 60 to 80) until about two days ago. Yesterday, he would only take about 20cc's in one sitting. Today, he took 20 the first time, 15 the next, and 40 on the third. I purchased Macaw formula with higher fat for him, and I took him to the vet today. The vet was concerned with how thin he is and told me I should take him back to the breeder to let her put some weight on him and finish weaning him. I've offered him exerything from pellets, seeds, nuts, monkey biscuits, weaning pellets, veggies, fruit, organic animal crackers... you name it. He will pick at stuff a bit, but really doesn't seem to ingest anything but the formula he takes. I have also tried to make eating a social deal... or to carry on when he does pick at his food.

Does anyone have advice? I am really about in tears at this point.
