Thank you Backyard Chickens first and foremost for creating and providing this website as a tool for us all! I have learned a tremendous amount of information here and feel the site is priceless to bird owners! Secondly, I have come into some information that has me doubting the breed of birds I acquired back in the summer. All the birds pictured were born this spring and have been laying eggs for a couple of months now. Of the five birds pictured, I'm 100% certain I have a barred rock, welsummer and cinnamon queen x white rock. What I'm afraid of is the remaining two birds which I thought up until recently were a black copper marans and blue copper marans. However, I have since questioned the identity of these two birds and believe them to possibly be a Black Australorp and Blue Cochin, and not the marans I thought I was getting. Again, they have been laying for a month or so now producing eggs daily and I only have one deep chocolate egg in the nexting box each day.... Can someone familiar enough with these two breeds provide feedback on any identifying traits that would determine the breed. Either way, I guess Im ok with it, but I sure was set on black and blue marans. the BA is a super sweet girl and I wouldnt trade her for nothing, but the blue is not so nice so she could be up for adoption. Thank you all for the help!!
