Regarding Shed & Goats
The area for the shed can be as follows (i.e. – 4200 Sq ft inside the Shed for protecting against Robbers in Night, bad weather+ 8400 Sq ft outside, this you can use for feeding the Goats in hay racks, water and relaxing)
Inside shed- 14 Sqft / Goat
Outside space- 28 Sqft / Goat
The information is for 300 goats but you can start initially with 25 or 30 and expand your live stock as money and time permits you. I am telling you since it is very hard to expand the shed in future so plan the area of shed and grow to the extent you can manage
Costs of the shed + yours and labour accommodation you have to check locally in your area but you can reduce the cost as per the site condition and availability of labour and material on time from near by locations.
For 150 Goats you need 1 Skilled labour + 1 Helper (Salary- 5500 for skilled + 3500 for helper)
You Should Purchase the Goats between October and April and go for Osmanabadi Breed
