First off, we ordered 7 roos this spring so we could choose which one we liked the best (the most beta of the bunch) and send the rest to freezer camp. We started yesterday trying to integrate flocks to see how the roos reacted to the older hens (age 1-4 yrs old). We put the roo in the coop at dusk. When we woke up this morning and let them out of the coop, his hind end had been so badly pecked we decided to cull him. We know this is a fact of chicken life, we take good care of our girls and give them lots of treats but know when enough is enough and culling them is the best option. I wonder if anyone has had similar experience integrating a young roo and older hens? what time of day or night to do this integration? also, as an fyi for those of you who will at some point need to cull a bird, we have found that placing them upside down in a "cone" (a piece of rigid plastic curled up and stapled to a wall where bottom opening is just big enough for the head to fit through, also google Joel Salatin's pastured poultry operation, we use the same cone type method). Once upside down, most birds become very calm. The cone holds the bird still, so it isn't able to flap its wings or escape. We take a VERY, VERY sharp knife, hold the beak in one hand and slice with some pressure along the carotid artery in the neck. This will bleed them out very quickly. There is twitching that happens, but this is an involuntary twitch that most animals have after they have lost consciousness. I think the most important thing to remember as a chicken owner is that there will come a time when a bird will be sick or injured and will need to be culled quickly to avoid distress. I know its hard to do and to think about, but the best way to honor your bird is to give them peace as quickly as possible. You gave them a good life, what more could you give them but a quick passing.
