I was given 2 chicks and 2 ducklings mid May 2016, they were probably 3ish weeks old. They are a good 2months old now. From pictures of other chickens, they seem to resemble the Thai's, am I right. The cock hasn't started crowing. I live in city limits, has anyone had success in the crowing level using the crow collars? I would love to keep him. My flock are becoming prettier and prettier each week. I love how he looks out for the flock. When the ducks go wondering, he has a special chirp looking for his gang.
