Budget 1.2–1.5 hectares. Most serious Senegalese operators lease rather than buy, which keeps capital free for birds and equipment. Expect to spend $22,000 on first-year lease deposit, land clearing, perimeter fencing, borehole drilling, and an all-weather access road. Keep your site at least 1 km from other poultry farms. That isolation buffer is the cheapest insurance you'll ever buy against Newcastle disease and avian influenza.

Senegal's Sahel heat wrecks sheds built without it in mind. Two houses covering 30,000 birds run roughly 2,200 m² of floor.

· Practical build: insulated steel-frame with concrete base, ridge ventilation, shade netting — about $48,000.

· Premium build: tunnel ventilation poultry house with evaporative cooling pads and automated climate control — $80,000.

Skip insulation to save a few dollars and you'll lose birds to heat stress every April. The cage and feed savings never make that back.

A turnkey H-type layer cage with manure belt, including feeding lines, nipple drinkers, egg collection conveyor, feed silo, egg grader, and backup power, runs $95,000 installed for 30,000 birds. Local manual cages look cheap on paper. They break 8–12% of your eggs, cause leg injuries, and pile manure that breeds pathogens. A proper automated battery cage system for layers in West Africa holds breakage at 2–3% and is rated for 20 years. On 30,000 birds, that recovery gap alone is several thousand dollars a month in extra sellable eggs.

Buy vaccinated, debeaked Lohmann or Hy-Line pullets at 16–17 weeks. At $3.30–$3.80 per bird plus transport and a 2% settling mortality reserve, budget $120,000. Cheap uncertified flocks tempt disasters: uneven maturity flattens your first peak, and one Newcastle outbreak erases the savings. A uniform, healthy flock is worth every franc.

Feed is your largest recurring cost. A 17% protein layer mash tracks global maize and soy. Thirty thousand birds eat about 100 tonnes a month. At $330–$360 per tonne that's $36,000 monthly. Hold four months of working capital — feed, wages, vet supplies — before the first egg sells. That's roughly $150,000 in reserve. Undercapitalised farms stall exactly when production peaks.

A lean team: farm manager, two barn attendants, one maintenance tech, one guard. Monthly payroll $3,500. Annual vaccination against Newcastle, Gumboro, and Salmonella plus biosecurity consumables runs $9,000. Electricity, water, litter disposal add $2,500 a month. Put these in the model — don't guess.

At Senegal's farm-gate egg price of about $0.10–$0.12 per egg and 92% peak lay, a 30,000-bird house yields roughly 27,000 eggs a day — around $97,000 monthly gross. After feed, labour, and vet, net operating margin lands near $50,000 a month. Tight mortality and feed conversion put full payback at 18–24 months. That math is why commercial egg production in Senegal keeps attracting serious money.
