Thank you for your advice. I guess I should have given you the whole picture.
I live in a strata block and have an area of 32 sq. metres down the side of the unit. The area is basically all weeds, but they have made a dirt bath down the end under the only tree. One size of the area is the building and on the other side of the wooden fence is open parkland. The birds free range in this area all day. I also have another area about the same size with artificial grass and a long narrow garden (see photo of birds in garden area) area that I occasionally let them wander about in, when I feel like cleaning up their mess they make.
I got all my supplies from Barter Chicken Farm who have been very helpful.
The birds have access to Vella Stock Feed Poultry Supreme pellets, which they eat and I have two water containers for drinking.
I read that treats should be only 10% of their diet, so I am trying not to go overboard with treating them. I tried some sunflower seeds which they did not like, but they like the sunflower kernels. Are these good for the birds, in moderation of course?
Thanks for your interest.
