I"d bought two babies of buff orpington when they were almost 20 - 25 years old. One male chick and one female. They both survived well in freezing winter but after they reach 2 months of age, male chick got his hairs grown and he became fat but the female got cold and loose motions. I gave her medication with the help of a vet. doctor and the loose motions stopped but she became so so weak. Her legs are very very weak as she stands up and sits again after walking 2 to 3 steps. Her feathers are also weak and sort of drying. She eats nothing but very very few grains of barley. i am worried about her. Please help.
