Hey folks, I added some cuckoo's last week to the flock and they look exactly like my older barred rock. Is this accurate or are these the same birds? My barred lays brown eggs right now (not dark brown) and so I will have to wait until the younger birds start laying. Are there some other differences I should see or can expect between the two variations? Oh well, any thoughts would be apreciated. Also any thoughts on these two types of birds?
