Branno..
We have 14 layer chickens here (White leg horns) and I have just started raising 45 day chickens for meat..(Family consumption) I will be able to give you accurate costings from start to finish in 27 days (or so)
Ive had the layers for 18 months and never had anything stolen and neither do I expect that I will in the future.. People are pretty honest around here in Bohol..
When you buy the layer chicks you will have to feed them from 4 to 6 months before they will lay.. You need to then feed them on layer mash which is around 28 Pesos per Kilo.. Medium/large eggs are 6.00/6/50 each.. Im not doing this with business in mind NOR WOULD I!!! (Been there done that) but its nice to be able to produce fresh eggs for the family at a reasonable price..(about 3.50 Pesos each) Chicken muck is dried and then goes into my raised vegetable beds..

Each section holds 15 x 45 day old birds.. Im hoping each will weigh at least 2 Kilos but really wishing for 2.5Kilo.. The reason we have four divisions is we are planning to buy 3 day old chicks every 15 days so we have a constant supply of cheap produce..

The layers are on the right of the picture (Semi free range?)
The floor is sloped so that the eggs roll to the front for collection..
Food tray is on outside and water tray pipe on far right.

45 days cages are different as the food tray is inside and water tray outside.

17 days old.

We also will also buy gabeer chicks (not sure of correct spelling).
These are like large English,French hens that can weigh as much as 7/8 Kilos after 4 months I think.. They also lay large brown eggs.. These will all be free range and fed kitchen scraps and cheap hog mash..

Cheers,
Fred.
