Ok so I thought I should update my thread.
DH and I killed 2 of the largest birds (by eye) today. It was easier and harder than I thought it would be.
Yesterday was exactly 8 weeks in my possession, The largest was a live weight of 8 lbs 2 oz and the second was 8 lbs even. Very pleased with those weights at 8 weeks considering I did organic feed with protein 19%. Not all birds are that big yet but I'm not killing all at once so.... that is ok.
We skinned and didn't save the neck (wanted to but fist time and all) but did save the liver, heart, gizzard. Getting set up and 'ready' took longer than the cleaning. I timed the second one and it took 35 minutes from coop to fridgerator.
Items used for killing:
We simply used a chair, a towel, a black tray (to catch blood), a plastic table, a trash bag, 2 sharp knives, a roll of paper towels, a large shallow bowl, 3 smaller trash bags, 2 gallon ziploc baggies and the hose. Items I didn't use cooler, kinda.
After we got one skinned and hosed off it was cool so I slipped it into a small trash bag and placed it in the fridge. I did use the cooler to put the liver, gizzards, heart in a ziploc bag and kept it out for adding more to the bag. I also put the feet in a ziploc bag and kept it in the cooler to add the others to.
Things that didn't go the way I would have liked. My meaties while retaining some chicken behaviors didn't use a standard coop ramp. I had an outside area for them to range in but the 12 chickens (not all of them) who would come down the ramp did not then later go up the ramp. So when I let them out of the coop I had to put them up. They didn't go up the ramp to eat, drink or sleep. I lost a few late in the game but they never had put on weight like the others I suspect they had something wrong with them genetically. They really do poop alot and I had to clean out the coop before they were done. I like the deep litter method and thought if they had outside time and area it would be less but they didn't get as much outside time as I would have liked. I would have liked them to have more greens/grass and bugs but the whole inside outside thing just didn't work well.
Somehow in the skinning and gutting I lost more than 35% of the weight. I lost more like 50%.
If I do it again the place they sleep at night will have to be closer to the ground. I like the idea of a tractor but my coop/range was very cheap to build because I just cut a hole in an existing shed for the coop and used free pallets to make a fence for the range the most expensive part of their range was the very large zip ties I used to tie them together. I used mealworms to boost their protein the first few weeks. They loved it but next time I'll use tilapia as I will soon have a supply of small fry hopefully. I won't keep them on the extra fish beyond 3 weeks so hopefully the taste won't be affected.
