About three weeks ago my Guinea hen hatched 11 cute little keets. This is my first time with keets so please bear with me. As soon as they hatched we put Mama, Father and chicks in a large brooder box because it was raining and I didn't want the keets to freeze. For the first 24 hours the family was happily scratching about and enjoying themselves in the brooder, and Dad would even help mama by keeping some of the keets warm. Well the next morning it seemed like dad had lost interest and was constantly trying to escape. So I let him out of the box and he instantly ran to the rest of the flock ( my flock is small only consisting of 3 males and a female). Since them mama has successfully raised the keets on her own. The dad hasn't had any access to them for the last three weeks. Well today I decided they could be let out to roam with their Mama as it is a beautiful sunny day. Mama happily showed her chicks how to dust bath and forage. Then along came Dad and the other two males. Mama was happy to see them and the keets were curious about these new adults. Together they all made their way down the back. Then things started to go wrong. The Dad started violently pecking at the chicks and Im afraid that he will hurt them. Is this normal behavior? Is it because they have been separated for so long? Thanks in advance.
