Temperament, calm and sociable. Never made notice if they were noisy or not. I would think no more so than any other. Eggs.... well.... when they are laying, they lay great..... when they are not.... they don't lay great. I have not had them laying for a year yet and I see a cycle. They will lay for 2-3 months like gang busters and then.... slow ..... waaaaaaaaaaaaaaaaaaay............down. Then pick right back up at full speed, then SLOW DOWN AGAIN. I would go hungry if I had to have them for breakfast. My Cuckoo Marans, don't seem to be that way though...... From 6 layers I get 1-2 eggs a day right now from the Blue and Black Coppers. When they are in full swing 4-6 a day.
Question to all the Marans folks-- I have noticed the same thing as DOnna. DOes anyone else have this cycling? If not, perhaps you could share your management style so I can change mine ! LOL
