We have a two day old lamb who is nursing like crazy, and mom is helping her, but she is not gaining any weight. Her brother and sister are doing fine, so it is not mom's milk. They are Finn sheep, so three lambs is normal. We supplemented with colostrum and drench, and she willingly took both, but it looks like she is starving to death. She is extremely thin and weak. Should we put her out of her misery? I hate to see an animal suffer, but don't want to cull her if she has a chance. She couldn't even stand yesterday, and is standing today. She was shivering yesterday, we put her under a light and put a heating pad under her. She is not shivering today, and feels warm. Her eyes were also closed for the first 24 hours or so, but we put a warm cloth on them today and they finally opened and stayed open, and are bright. She baas normal, and doesn't seem in pain, but she seems very hungry.
