Morgan7782, I have 1 Delaware cockerel from Mcmurray. He is only 12 weeks old, so I have very limited experience. So far he is a very confident, quiet roo. As compared to the BO roo that is the same age. Ellis, the del is dominant but in a very quiet self assured sort of way. The BO tends to get his hackle feathers up at any activity of the girls, and seems to run around yelling at them for the littlest issue--- where as the Del just calmly steps in between the tiffs and keeps the girls in line with quiet movements. He always stays between the dogs (outside of the pen) and the girls, and already give the girls the first dibs at good treats. I just love my little Ellis. I keep hoping and praying that his personality doesn't change.....
As for other hatchery dels, I think there is a very mixed bag.
