When they first start to lay, yea, they do lay a nice shade of brown egg.... But, I must be honest, as mine have slowed down (they only lay for 1 or 2 yrs.), they are now laying a VERY VERY light brown to pink egg. And most of them are mishaped or broken. I have lost a number of these to internal laying and other various egg issues. Honestly, they are overall friendly birds but I can't recommend them to you because of the problems that I have had with them.... I just don't think it is fair that somebody was careless enough to create a breed that produces soo many eggs that they sometimes die from it and believe me it is horrible to watch them suffer, try to save them, and then they die anyway.
Hope you make the right decision,
JB
P.S. I got my Comets from Mt. Healthy. And I chose my username BEFORE they were old enough to lay so I did not know of the problems with them yet...
