Not really sure what is available in your area. I would suggest finding and feeding them something EQUIVALENT to ALFLOCK. Check your feed store,,, and see what they have..

That is what I feed my flock. It is ideal for more than just chickens, (hence Alflock) It is 18% protein and 2% calcium. Layer feed is similar in protein or slightly lower. The lower protein is to keep costs down, Like at 16%. Layer feed is also formulated with 4% calcium. That is fine as long as your chickens are laying EGGS. Non-layers, and roosters are somewhat harmed with that much (
processed) calcium. It affects the health of their kidneys, and liver.
When you provide the 18% Protein, and 2% calcium, it is also good to provide Cracked Oyster Shells freechoice. The chickens will seek out what they know they need. If your chickens free range on grass and other greens, they will also supplement their calcium needs from these plants as well. The free choice Oyster shells are such,,, that chickens will
not OVERDOSE on calcium. Anything not needed in the digestive trak will just go thru the chicken out the south end

Ask anything else you are not sure of.. There are numerous peeps here willing to share advice as needed.
WISHING YOU BEST,,,,,,,,,,,,,,,,,,, and
