I had/have a sick chick (Daisy). I separated Daisy from the flock 12 days ago and she's been getting better. Today I moved the others into the coop but decided to leave one of the calmer ones (Halo) behind and put them together to start warming Daisy back into flock life. Halo is now picking at Daisy's tail feathers and bullying her around a little bit. Thoughts, comments, concerns? Thank you in advance for the help!
