So, I have a flock of 17, with one mini rooster. Yesterday a gal gave me a Bantam White Cochin and I love her but she's not eating or drinking. She has very little activity with the others, she just hides a lot. Idk what to do. The gal that gave me her has another Cochin, so should I go that route or should I give it back. She is the only mini bird in my flock besides the rooster.
