Hey everyone..I'll introduce myself later...I'm new to goats (like a week new) I have nigerian dwarf/nubian mix 3 year old doe. Bought her literally one week ago today. She had a buck and he was weaned..At least 3 weeks possibly longer. Well her udders are turning blue. Going to attach pictures. Can anyone tell me I'm crazy and it's nothing to worry about or what do I do? The bottom of her bum is kinda blue also..pretty sure it was pink. Thanks so much in advance!
