I got a supposed barred rock from a breeder but it isn't a barred rock, she's about 6 months, laying brown large eggs, I just don't know what breed or breed mix she is. Her comb is naturally folded over, she is very healthy and its bright red, but has been flipped over for months.
It is quite common for combs to flop over - if you can capture a photo in better lighting so that we can see the bird better we can help you to identify her breed as what can be seen leads to a couple of possibilities.
