So 240ml for a 4.5 lb chicken sounds about right? I must say, this thread has been a wonderful source of information and without it I am pretty sure my Sophie would be dead. I was terrified of trying to tube feed her, but figured if I didn't try, she wasn't going to make it. There is NO way you can syringe water by the dropper to a bird and get anywhere close to enough fluids in them. After the first couple of times, it became much easier and it only takes a couple of minutes. Thank you to all who have contributed to this superbly helpful thread.
