Her mom was either a blue bkack ee or a buff laced ee, her dad is bean line f2.
This is my newest line of ayam cemani f2 from gff.
Generally "locals" are cheap and consider all chickens "just a chicken" and don't appreciate the value of a rare breed chicken. Greenfire Farms sells day olds for $200. Do they worry if any of those chicks might not be breeder quality? As long as you accurately describe the birds, like you did here, then the buyer can decide if they want them or not. Judging from your pictures you have a decent pair with the same minor flaws as most everyone else's Cemanis. I wouldn't sell them for less than you paid for them. If this was my pair I would list them initially for $600 for the pair or $200 for the male and go from there. If you want to breed them yourself, at least give the no crow collar a chance before you part with him/them.
