So I weighed the KK's today for the first time in 2.5 weeks. It's impossible to weigh them during the week because of the short length of daylight hours, and our weekends here lately are so busy that weighing meat chickens isn't a very high priority.
Here are this week's weights:
Hi - 67.9 ounces, Lo - 41.8 ounces, Avg 55.31 At 8.5 weeks our FR's averaged 76.8 ounces. However, by 8.5 weeks our FR's had consumed about 650 pounds of food while our KK's have only eaten 450 pounds of food. Overall the feed conversion of the KK's is 2.51 as compared to 2.71 for the FR's, so even though they're smaller, I'm still pleased with their growth.
And I can't blame the birds for slow growth. They haven't eaten as much food as the FR's did up to this point partially (I think) because the days are shorter, and they have fewer daylight hours in which to consume food, and because I haven't poured the food to them quite as heavily as I did the FR's. This weekend we finally got 2 PVC pipe feeders set up for them which holds about 10 3 qt scoops of feed as compared to the smaller feeders which only held about 3 qts of feed that we filled 2 times per day.
We also moved the KK's to our front yard to give them more room in which to range. Their old 10 X 20 pen just wasn't cutting it anymore. Plus it was really starting to smell. Now I just hope that the hawks don't carry them off. There is quite a bit of tree cover in the front yard, but I just lost a young Silkie last week, so I'm kinda nervous.
We have lost 2 KK's in the past week and a half. One I found in the coop just sitting around not moving, so I brought it in. I acted like it had some sort of leg issue, wouldn't eat, wouldn't drink, and it died less than 24 hours later. The other I found this morning dead in the coop by the feeder, being pecked over by his siblings. yuck! Our weather of late has been damp and chilly (40's - 50's for lows, some mid 30's.) so I don't know if that's what's attributing to these losses or not.
Here are some pics of them in their new "digs":
