Hi, I new to this board , so please bare with me. I am looking to find out how to introduce my new chikens with my old. My friend who owns chickens said to do it at night, in the dark, and they would be fine in the morning, thats what I did and it did not work. I got up this morning to find two of my new chickens are bleeding on their heads. I really need some help. I have them all seperated right now, but its going to rain soon, so the new ones are going to need some cover. PLEASE PLEASE Advise! Thanks so much!
