Ok, yet again demonstrating my lack of knowledge or as Naam likes to put it, my "Wealth of ignorance" ( I should be rich by now, woot!)

If i want chickens for both meat and eggs and lets make the following assumptions;

Proper farang chickens, no native thais

I want to harvest 50 chickens a year for eating

I am not using any mechanical incubators

How many chickens do I need to have a sustainable flock?

How much will it cost to feed these chickens?

What sort of cost offset against feed will excess egg production provide at he local market or in barter with the natives?

How much poo is gonna be involved and can I throw it all in the green pond?

I think its better you do some reading as this would take an age to answer everything

for meat and eggs take pure rhode island reds they hatch there own young every now and then and still lay well males make 4kg-5kg

If you buy 100 day old chicks 50% will be males there is your 50 a year and by the time you get to the end your hens will be making more babys

There are no other birds to chose from at this time in Thailand that will do as well as pure RIR
