I'm dropping off three of my five birds that have died of some disease in the past month. The vet I communicated with said that it would cost $85. I'm guessing that's the cost for all the birds, right? Not individual? Also, I know you're supposed to refrigerate the bodies, but I left mine outside in the correct temperature, and then the temp. dropped. So now they're all frozen. I'm guessing it may be harder to determine the cause of death, but it won't be impossible if I thaw them out? Is there a certain way I should do it? Thanks in advance.
