Wonderful birds I got a pair for breeding and these birds are just wonderful. They look real nice if kept clean and the cocks have long sickle feathers. But hens in the breeding pen with the cocks can step on there sickle feathers and make them look ragedy. Also there feathers come out a little easier than most birds so dont try and grab them. Also when buying adult birds it will take some time for them to become tame for you because Sumatras are a little flighty.
