It seems slightly mad that as I write this it’s hot outside, but now really is the time to think about the change of season. Autumn brings warm days and chilly nights, and then winter rolls in with that British cocktail of cold and wet that makes broiler growing such an “interesting” occupation.
With lower-density flocks, the welfare benefits are clear, but the sheds won’t quite run themselves. A few key reminders will help keep your birds comfortable and your stress levels (relatively) low this season.
Turn Up the Heat
Fewer birds = less natural heating. Imagine losing a few radiators at home, it suddenly feels colder. Preheat those floors properly; concrete is a world-class heat thief. Keep a close eye on brooding temps (remember, too much heat early on is just as bad) and make sure heaters are doing their job.
Ventilate, But Don’t Refrigerate
Ventilation is all about removing moisture and ammonia without turning your shed into a wind tunnel. Cold air from outside should mix with warm roof air before it heads down to the birds. Trust your eyes and nose as much as your shed sensors.
Litter Matters
Lower density usually means drier litter, but don’t relax just yet. Cold patches will still cap, especially around inlets and areas of dodgy insulation. Spread it evenly before placement, and keep topping up before problems set in.
Bird Behaviour – The Real Feedback System
Your birds will always tell you what’s going on. Huddling in clusters after 48 hours post placement? Too cold. Panting or pecking walls? Too hot. Uneven spread? Drafts. In lower-density flocks, these signs are more subtle—so it pays to be sharp-eyed.
Service Season
Now’s the time to clean and calibrate probes, service heaters and fans, and test those back-up systems. Winter is not the season to discover that “heater three” is purely decorative.
Energy Economics
Lower density means more heating per bird. Insulation and well-managed ventilation are your margin’s best friends. Check for sneaky leaks, double doors and gable fans are usual suspects.
While I’m personally glad we’re edging out of this heat, I know the cold, damp months ahead will add a new twist to growing broilers, especially with the new 30kg programme. Best of luck, and may the odds be ever in your favour.
