My favorite Orpington has gotten me worried these past few days. Yesterday she was favoring 1 day but it seemed like that healed over night? Now I've noticed she has a purple tipped comb and it's cold. It's not cold here. It is very windy at the moment. She is 2 1/2 years old. She's been eating here and there. I literally can't sleep over this. Please any ideas? Thanks in advance
