I feed Barastoc, which is a pellet. I am not sure what is available in your area. It will depend on your birds. Some chickens like ISA must get a very high density pellet, or they can actually perish from malnourishment. They have literally been bred to eat pellet and to lay an unnatural quantity of eggs, so if you feed them seed based or lots of fresh they struggle to get what they need- blows my mind! Poor chickens.
If you have a bird that is laying everyday you need to feed something that can replace the calcium and energy loss. If your hens isn't laying daily you can feed a maintenance diet. Some people suggest feeding a pellet grower during the times of molt, but again it depends on your bird.
I like barastoc because they have many options and you can get exactly what you need for the stage of your hens life. I have an older hen who hasn't laid in a long time and then two little bannies, who rarely lay, so it doesn't make sense for me to give them the "top layer" pellet.
