Hello Everyone!
First time poster here, though I've been lurking for a long time gleaning wisdom from all of you:) I guess a quick backstory is in order. I grew up on a commercial broiler chicken farm and spent my youth cleaning out the barns and burning out my sense of smell until I graduated and as quick as I could, I ditched the boring farm life for the glitz and glamour of the big city. Only, I soon learned that the farm life that I complained about as a kid was paradise to what life was like off the farm in the city. I moved back to my home town, opened a movie theatre, and ran that for the past 14 years as I thought of ways I could get back to the country. During those years in town, I was able to get the town council to allow urban chickens (4 max, no roos) but 4 chickens was not enough.
Long story short, I recently sold my theatre and have used some of the money to buy 20 acres of agricultural land which I hope to raise poultry using the paddock system. Here in Alberta, farmers can have up to 2000 meat birds before needing to buy quota and so that is the long term goal in terms of numbers, but I realize that will probably take me a few years to get to that:) However, since the land is clear except for an perimeter fence, I want to plan for the 2000 birds now so that any building I do has the end goal in mind. Most of the discussions on raising chickens here in the forum seem to be focused on a lot fewer birds than 2000, but I'm hoping that any advice is scale-able.
I was thinking of fencing off approximately 6.2 acres (though that number is flexible to an extent), divide it up into 9 roughly equal parcels and move batches of up to 300 birds through them (moving them to a new paddock each week). I'd build a small barn with a large run for a base flock of layers from which to get the meat birds from, so using a large cabinet incubator I should have roughly 300 new chicks every 21 days (minus mortality). Once the next batch is hatched, they go into the brooder, the first batch would be taken out to the first paddock where a mobile coop awaits, and the cycle begins again. I know Cornish Cross X are ready to process at 8 weeks, but I'm looking at getting Sulmtalers as I've heard they are a very tasty bird and while I can't find information on when they are ready to process, I've been going with 12 weeks (so if I'm wrong...someone please tell me!:)
With this system of rotating paddocks, a maximum number of 300 chickens would be in an area of about 0.7 acres for a week before moving on to the next. That paddock would then have 2 weeks of rest before the next group went through. After six batches of chickens, no more would be hatched and the land could rest until next spring. Incubating would start the beginning of April and end beginning of July, and the foraging would start early May and the last batch would leave to be processed beginning of October.
That's the plan, but I have no familiarity with raising chickens in this manner before. My experience growing up was the commercial system where we had 50,000 raised in a barn for 7 weeks and then shipped off in the middle of the night in tractor trailers. My 4 backyard chickens count for very little too as town bylaws prohibit me from building a run larger then 100 square ft so obviously there isn't anything left in there for them to forage.
Is my plan doable? Would 300 birds (and that is the absolute upper limit, hatching mortality would bring the number down quite a bit I imagine) turn 0.7 acres of grassy field into dirt in a week? Is 2 weeks of rest for each paddock enough rest? I should also add that my current job is shift work away from the land and so if I'm gone for a few days I'd like there not to be too much work for my wife to have to take over, which is why I'm more interested in the paddock system vs. the Joel Saladin chicken tractor method which has to be moved once or twice daily.
Thoughts from you all? Doable? Foolish? If I need to move in another direction for raising my chickens, it's good for me to hear now when I've only got a handful instead of the full amount:)
Thanks in advance for any advice you have!
