It's been a few years since I processed any Dark Cornish, but I think they dressed the same as any other chicken; the Cornish crosses I raise every year are light but then again they only reach 8 weeks of age.
I would say they reached their full size around 9-10 months. I've only had one Dark Cornish go broody, and she is from an older batch of hens from McMurray, but she was a good setter, good mama, and the sweetest thing. Lets me tote her around, tolerates the dogs, very calm.
They are about 14 months old now, and I would say they are closer to 5-6 pounds than the stated 8 pounds on McMurray's website. I'm butchering meat birds this weekend so I could weigh a couple of them when I have my scale out, and get some better pictures.
Here's a recent picture of them in a...
I did process the roos, and they were good, around 3.5 pounds by the time I did them at six months. Easy to pluck. (The hardest to pluck were the Barred Rocks. So. Many. Tiny. Feathers.)
Mine are definitely bigger than that, they are rounder and more filled out. I think they are slow-growers, mine took forever to reach maturity. I like to describe them as prehistoric feathery bowling balls. Their bodies definitely have a round shape to them with a wide tail.
I have Dark Cornish from McMurray, and I do think they are a little on the small side, BUT, they are nicely shaped and have great dispositions. Very sweet and docile birds, not flighty or skittish. One of mine even became broody and hatched chicks.
I have 7 or 8 Dark Cornish hens, all from McMurray. They are on the smaller side (as are most of the hens I've received from McMurray, except the Partridge Rocks which are huge!) but they have a very nice temperament and are very docile and are all shaped nicely. I have found some other...
That has been my experience with McMurray as well...definitely hatchery stock and small adults...except for the Partridge Rock hens I got which are huge. The two White Rock hens aren't badly sized, and I'd like to find a Dark Cornish roo to pair them with, but am wary of getting any more chicks...
My broody abandoned the nest around day 13-14, and by the time I realized all the eggs were gone. Not sure what I will do different the next time one decides to go broody. Isolate in the rabbit hutch? Just keep taking the eggs and not let her set? Not sure I can handle the heartache of losing...
It appears my broody has abandoned her nest. Today is day 15. Yesterday she was off a good portion of the day, but other hens were in and out of the nest box laying most of the day. I was able to coerce her back on the nest last night, but I don't know if she stayed on or not. Tonight when I...
Update on my broody hatch: Yesterday was day 11 and I candled for the first time. There were 17 eggs in the nest, 2 were tiny first layer eggs that snuck in there when I wasn't looking, and weren't developed so I pulled them (determined by candling and confirmed after). Saw 8 or 9 embryos out of...
Can I play? One of my six month old White Rocks is setting on seventeen (!!) eggs. She's been on them for eight days now. Haven't candled yet. I only have one roo, so I'm not holding out too much hope.
I have two White Rocks and two Partridge Rocks, all around six months old (February hatch from McMurray). One of my White Rocks is setting on 17 eggs right now. I guess it just depends on the bird! Have to see if she goes broody again in the future.
These two were part of McMurray Hatchery "rainbow layer" chicks from earlier this year, with bonus "exotic" chick. I have identified all the other breeds (white leghorn, brown leghorn, red leghorn, dark cornish, partridge rock, minorca, dominique, buff orp, light brahma) except for these. My...
