I've had them on CL for weeks, no takers unless I hand deliver them 2 hour to these people...yeah, no thanks. I'm 99% sure my Delaware is a roo...he is massive, has barred feathers on the tail, and the biggest comb and wattles of the bunch.Welcome MN Chicken..... Are you sure those are all roosters? Your Delaware rooster looks a lot like my Delaware hen. I have never seen a Delaware rooster so no idea what they look like.
If you do not want to do the deed yourself, those chickens would go fast on Craigslist. I know when I put "normal" roosters (non-CX) on CL they are gone in a day. We have a large enough Asian population in the area that love their scrawny roosters. There is a woman my wife works with that will take most of ours now. I mean those I do not want.
