I have a 10 yr old ewe, and she can't get herself up without me picking her up. She's not been able to do this for 5 days now, think her old age is kicking in. She's looking fairly skinny. I'm checking on her every hour but leaving her at night. She's eating ewe nuts fine. Do you think it's time to end her life or let her keep going? Any advice would be greatly appreciated. Cheers
