Hi, I had a rooster and hen around 4 months old. I was not sure if I was going to keep the roo or not so I got some baby hens to keep my hen company if I did rehome the roo. Well when the babies came we kept them in a holding pen inside the coop for 24 hours. They had plenty of space, food and water. So today we let them out to see how the older ones did with them and the roo started pecking one of the babies pretty hard and jumping on their head!! I am new to chickens and this was horrifying for me. My husband was in the pen with me and we supervised to make sure the lil one didn't get hurt. Is this natural behavior? The roo seemed very aggressive and I felt so bad for the baby. My older hen was following the roo and looked like she was protecting the babies but then she started pecking at them but not nearly has bad as the roo. Well we took out the roo, and left her with the babies, she calmed down but every now and then she pecks them and charges them. She went to roost in the hen house and they were going to roost on the hen house, but I moved them in the hen house with her. she didn't do anything but I am concerned in for in the morning. Should I have not let them in the hen house? Also I am concerned for my older hen cause the roo was her only mate and friend before the babies came but we took him out of the pen. Will she flock with the babies or did we just single her out? Any advice is greatly appreciated. Thank you!
