Consider the local weather/climate conditions in relation to the stages of growth of the broiler chickens.
This is really a past lesson learned that I’m quite pleased to say I conquered this year, as I think it went better than it has done in some time. Maybe I had a little luck, but let’s go with learned lessons.
I have finally learned to work with the seasonal temperatures instead of against them. Instead of trying to brood chicks in the early spring, when I have to keep the heat lamps going for a couple of weeks, and delay putting birds out on pasture because it’s just too darned wet, I now brood them when it’s super hot out – I can turn the heat lamps off for chunks of time in the middle of the day and help the birds acclimate comfortably to living without that red glow. When I do that, the ground is automatically drier, the hay has been taken off weeks before so that there is new grass growth, and the birds can go out on pasture when we’re still not getting much rain. They are going out on pasture younger, so are quite happy in the heat still, and by the time they’re a few weeks older and liable to suffer from heat stress, we’re getting cooler nights, and they day temperature comes down a notch or two.
Believe me, this took a lot of hard lessons before I got it figured out. We lost more than 50 birds one May due to a surprise cold snap – we had a sub 0 C night, and I had eased up on the temperature in the brooder as I started acclimating the birds in readiness for going to pasture later the next week. Half the batch got chilled, developed pneumonia and died – a needless waste of life, and a costly way to learn. Another time, we had such a wet spring, the hay couldn’t be cut – I had birds in the brooder that didn’t make it onto pasture until 8 days before processing – and my brooder was most definitely not big enough to hold them properly when they were mature sizes. I’ve had years where brooding went fine, getting out on pasture went fine, but then as the birds got close to butchering weight, they started to keel over from heart attacks due to heat stress.
Recognizing that only raising birds at the end of the summer season limits production, there is possibly more lesson learning to be done here though. There is also the factor that twice now, I’ve had difficulties with processing so late in the season, because the processor is switching over to turkeys – Canadian Thanksgiving is the second weekend in October, and they do turkeys for about 10 days before that, plus time to recalibrate the equipment. I’m debating doing a small batch in June/July, and then doing my main batch as usual. Or maybe doing 2 batches Aug/Sep, but staggered so that they don’t overlap on the field (I only have two shelters and I don’t want to be moving 4 at once every morning anyway). That would require a degree of planning that I’m clearly not currently practicing, so we’ll see how we go next year on that front.
