For 5 lakh taka, you're not building an environmentally controlled shed or installing automatic feeder lines. What you can do is set up a small commercial broiler farm with 500 to 800 birds in a semi-controlled setup.

Here's where the money goes. A basic open-sided shed with concrete floor and drainage for 800 birds costs 1.5 to 2 lakh. Day-old chicks run 28,000 to 36,000 taka. Feed for a 35-day cycle — the biggest line item — takes 1.8 to 2.2 lakh. Manual drinkers, feeders, and heating lamps add 25,000 to 40,000. Vaccination and basic medicines run 10,000 to 15,000. Litter, disinfectants, electricity, and labour round out another 45,000 to 70,000.

At this level, you're doing most of the work yourself or with one hired hand. Profit per bird ranges from 40 to 80 taka. A good cycle puts 32,000 to 64,000 taka in your pocket. But a disease outbreak or a feed price spike can wipe out your margin entirely.

Run five cycles a year — realistic for semi-controlled housing in Bangladesh — and your annual return lands between 1.6 and 3.2 lakh. Against a 5 lakh setup cost, that's a payback period of roughly 1.5 to 3 years. This is a testing ground: a place to learn feed conversion in practice, build relationships with chick suppliers, and understand what mortality management actually requires before you scale.

Fifty lakh puts you into a different bracket entirely. You're no longer a smallholder — you're a commercial operator competing in a national market.

Your capital infrastructure breaks down like this. An environmentally controlled shed with insulated roofing, concrete flooring, and full drainage for 10,000 birds costs 22 to 30 lakh. Automatic feeder and drinker lines run 5 to 7 lakh. Industrial exhaust fans, cooling pads, and automated climate control add 4 to 6 lakh. A gas brooder heating system costs 2 to 3 lakh. Bulk feed storage with 8 to 10 ton capacity runs 1.5 to 2 lakh. Generator backup for uninterrupted power to ventilation adds 3 to 5 lakh. Total fixed investment: 38 to 53 lakh.

Working capital per cycle is equally substantial. Feed for a 35-day cycle — 35 to 40 tons — runs 18 to 22 lakh. Chicks cost 3.5 to 4.5 lakh. Vaccination, litter, electricity, fuel, labour, and biosecurity add another 3.5 to 5 lakh. Total operating cost per cycle: roughly 25 to 32 lakh.

Profit per bird in a well-managed 10,000-bird operation ranges from 50 to 90 taka. A good cycle delivers 5 to 9 lakh in net profit. Run 6 cycles per year under controlled environment conditions, and annual returns land between 30 and 54 lakh — a payback period of about 1 to 1.8 years on your total investment.

Remember: you need working capital reserves to cover at least two full cycles. A disease outbreak or a corn price shock in your first batch won't end you if you have reserves. Without them, one bad cycle can shut you down.

Here's the line item that bankrupts more poultry farmers than any other: management inexperience.

When you have 10,000 broilers under one roof, you don't guess brooding temperature. You don't "see how things go" with ventilation settings. You run a strict vaccination schedule, monitor ammonia levels daily, and track your feed conversion ratio like your business depends on it — because it does.

A well-managed farm with 10,000 birds will outperform a poorly managed farm with 30,000 birds every time. The money you spend learning — on vet consultants, on staff training, on proper shed design before you pour concrete — is the cheapest insurance you'll ever buy.

If you have 5 lakh and limited experience, start with 500 to 800 birds. Run three or four cycles. Learn what coccidiosis looks like. Learn how broilers sound at 3 a.m. when the power cuts. Then scale.

If you have 50 lakh and you've done your trial cycles, you're ready for a 10,000-bird commercial operation. But don't pour every taka into infrastructure. Reserve at least 30% of your capital for operating costs and emergencies. The question isn't how much money you need to start. It's how long you can keep running if the next batch goes wrong. If you can answer that, you're ready.
