Ikiwa unafanya vizuri, hatch rate inafika 80-90%.
Hapa ni step-by-step:
A. Kabla ya kuweka mayai - Prep
1. Chagua mayai mazuri: Fresh, 2-7 days. Safi, shape sawa, no cracks. Weight 55-65g kwa layers/broilers. Usioshe.
2. Store: Pointy side chini, 15°C. Zigeuze mara 1 daily. Usizihifadhi zaidi ya siku 10.
3. Incubator: Clean + disinfect. I-warm 12hrs before. Target: 37.5°C na 55-60% humidity kwa siku 1-18.
B. Siku 1-18: Development stage
1. Joto: 37.5°C constant. Joto juu = vifaranga wanakufa. Joto chini = wanachelewa.
2. Humidity: 55-60%. Weka maji kwa tray ya incubator.
3. Kugeuza mayai: Mara 3-5 daily. Automatic incubator inafanya yenyewe. Hii inazuia embryo kushikamana na shell.
4. Candling: Siku 7 na 18. Shika flashlight. Mayai mazuri kuna mishipa + black spot. Toa yale clear/ameoza.
C. Siku 19-21: Hatching stage
Hii ndio muhimu sana:
1. Stop turning: Siku 18 toka mayai kwa tray ya kugeuza uwaweke flat.
2. Ongeza humidity: 65-75%. Inasaidia shell ilainike vifaranga watoke. Maji zaidi kwenye tray.
3. Punguza joto kidogo: 37.2°C
4. Usifungue incubator: Ukiifungua humidity inaanguka na membrane inakauka. Vifaranga wanashikwa ndani.
5. Subiri: Wanaanza kupepeta siku 20. Siku 21 wengi watakuwa wametoka. Wape masaa 24 ndani ili wakauke.
D. Baada ya kutoka
1. Brooder: Weka vifaranga kwa brooder 32°C wiki 1. Chakula = chick mash + maji + glucose.
2. Usitoe mapema: Acha wakauke vizuri ndani ya incubator masaa 12-24.
E. Makosa 4 ya kuharibu hatch:
1. Joto fluctuates - Stima ikikatika = shida. Tumia inverter/UPS.
2. Humidity chini siku 19-21 - Vifaranga wanashikwa ndani "shrink wrapped".
3. Mayai machafu - Bacteria zinaingia na kuharibu wote.
4. Kufungua incubator kila dakika - Kuwa na subira
Gharama estimate Kenya Shillings 2026 budget:
Incubator ya 528 eggs:
Manual 25k-35k
Automatic 45k-65k
Stima per month 2k-4k
Cost per chic unaunda na 40-50
