Random thoughts.
Ingredients... I never use soybean meal... .
I sell a LOT of eggs and a LOT of meat... it's my business.
Many of my customers refuse to eat anything fed soy, or anything fed any gmo ingredients (lots of WAPF customers).
That said... soybean meal is also not animal protein.
I could go on... let's just say I hate soybean meal.
Field peas will bring the protein level up some - I love field peas.
But again, animal protein is necessary... so my grains are primarily corn, field peas, and oats and I feed fish meal for chicks and BSF for adults (BSF have too much calcium for chicks). I am raising enough BSF right now that I am freezing batches daily so I'll have them to feed over the winter. I wasn't certain with our late spring that my production would pick up enough to double the output I needed for winter feeding, but it finally has and I'm teaming with BSF right now.
=.
As far as how to feed CX... I have found over the years arguments for every type of management system out there.
I've tried it all.
I think the "kiss" method works best... keep it simply stupid.
Raise them in the fall or spring when temperatures are moderate. Feed a good quality feed. Walk away.
There is no reason to make growing out CX a complicated matter... I've made it complicated... it doesn't have to be.
I put fresh feed out daily, top off the big PVC waterer that has chicken nipples on the bottom, and walk away.
In 8-9 weeks (usually mid-Nov), we slaughter... it's brainless.
I simply do not like the idea that CX are not self-sustaining, so that is one of several reasons I am raising a more dual purpose bird - I'd like to get away from the CX. I considered Freedom Rangers, but they are not self-sustaining either being a hybrid. I know a few who have tried, they simply do not breed true worth a darn.
I fed out 42 CX last time... didn't loose one... didn't have one problem. Nothing special, no extra vitamins other than the nutribalancer I added to feed.
I balanced, ground, and fermented a good quality ration that was 20% protein (very similar ration to what I feed my chicks), made sure it had enough animal protein in it, and free fed for 9 weeks - slaughtered all 42, they all had great fast growth and great looking organs (the ultimate test of a slaughtered animal's health).
I can "claim" they free ranged... but trust me, by week 4 they never wander further than the feed pan and waterer - which I always put in different places to just make them get some exercise. So yes, they can go where ever they want... they just have no reason to.
I don't have to worry about predators since I have maremma, so everyone free ranges... I have a momma and 3 week old pups with the chickens right now (start the pups with chicks and then move them to larger livestock and they will easily come back to be good poultry guardians as adults).
In my experience, depriving CX of feed 12 hrs out of the day just makes them gorge the remaining 12 hrs... that creates other problems - lots of them.
I've done it both ways. They eat less over the 8 weeks if they free feed than if I dole it out, and they grow better.
It's a lot like feeding bottle lambs... I have fed out as many as 300 in a 60 day period when I owned the sheep dairy - free feed milk milk replacer and they don't gorge, don't have health issue, and eat less.
Feed pans... for anything fermented I avoid any metal that isn't stainless steel.
Leaching can be a problem... I'm a cheesemaker, so I'm a little weird this... but I only use food grade plastic and stainless for feeding FF...
I have toyed with the double bucket method for FF, but have never tried it.
Mostly I'm worried about the weight of the top bucket when lifted out.
Has anyone had trouble with this? Seems like a lot of dead weight lifting that much... I tend to have this philosophy as I am not as young as I used to be... work smarter and not harder. I just have no desire to dead lift 50 lbs on a daily basis.
I currently feed about 20 lbs of FF a day ( have a LOT of chicks I'm growing out this year), so I have FF in 2 buckets all the time.
Before I get to serious cockerel culling this fall I will be feeding about 35 lbs/day, so I will be adding a 3rd bucket shortly.
If I didn't grind and mix my own ration I could never afford the $20 or more for a 50 lb bag of quality feed that some folks are paying... I understand some in the closest city to me a few hours away are paying $33 for a bag of organic layer.
I can't imagine! I love my job, my livestock, but... it's not a hobby and I can't afford to loose money. Animals that do not pay for themselves quickly leave our place. As my husband likes to say, "We have 2 requirements for you to live here... you have to have shoulders, and you have to have a job."
