Bea-Dominique, Olivia-dark Cornish, Gwen-golden sex link, Edith-barred rock. Any of them look suspicious? Thanks!
The bird in the first set of photos is not a Dominique. It appears to be a cuckoo marans as it has a single comb and feathered shanks. Dominiques have rose combs and clean legs. I would also say that it's a cockerel from that comb and wattle development.
