Pros: Pretty, Brave, Sweet
Cons: Bad in cold weather
I got a Sumatra rooster a few years ago. He was the most handsomest and bravest rooster ever. Once a hawk swooped down to get his hens and he fought off the hawk talon to talon until it flew away. He never tried to chase me and he was always gentle with the girls. He chased off the other rooster sometimes, but that's normal. They didn't get in any major bloody fights or anything. He died protecting his flock from the dogs that attacked and he did save his favorite hen.
I then purchased three Sumatra chicks. I had them in with the other chicks I bought and they didn't do as well. So I'd reccomend keeping them with bantams. I did that and the remaning chick grew until she was laying age. I don't reccomend them for cold weather climates. I live in MN and even though I had the heat lamp on in the coop she got really cold and passed away sadly. She was very sweet and ever since she was a chick she would perch on your arm. She didn't mind behing held.
I highly reccomend this breed to anyone! If I didn't live in MN I would definatley raise a flock of these!
