A friend has a friend.... this is the situation. They had chickens and a duck. Over time they had 1 chicken left and the duck. The duck and chicken had a very strong relationship to the point that the chicken would roost under the duck's wing at night. Sadly, the duck died 4 months ago and now they have a lonely old chicken. They tried bringing in another hen who promptly beat up the older hen so they sent that chicken back where it came from. They don't want a flock but I felt they need at least 2 others to avoid this situation from repeating itself too soon. Questions: Should they try: young chickens? old chickens? an old rooster? Guess they still want to keep the old gal but feel bad cause she's all alone. I feel bad too but don't know what to tell them. All suggestions, ideas and recommendations appreciated!!!
