Hi - Our first baby chicken ever born at our house named Miracle is 4 months old. She is fully feathered and has been very healthy until yesterday (12-14-16). She appeared to be walking funny, like sort of sluggish and she is lifting her feet REALLY high for each step she takes. This morning she did not come for breakfast. I found her huddled in a corner by herself. She is lethargic. I tried to dip her beak in water. She doesn't resist but won't drink either. I put her in a little area of the coop by herself with some food. She half heartedly tried to eat but never really did. It is negative 7 this morning here in Iowa. I put her in a guinea pig cage and brought her into the house. I don't know if she's just really really cold or if she has something else. If anyone has any ideas, please tell me, We love our little Miracle. Also, all other 27 coop-mates seem healthy and fine.
