Thank you both for your warm welcome. I have 2 hi-line brown hens they are about 7 months old. I am feeding them a layer pellet mix I buy from local farm supply place as well as a few scraps from the kitchen. The pellets are in one of those feeder things. They are very fussy and only want to eat the wheat and only eat the pellets if nothing else. The chickens had the run of the back yard but completely stripped the back lawn and all the garden beds, we don't have any weeds anywhere. My Dad recently made them their own section fenced off from the rest of the back yard. Their coop is still the same.
We live in Perth (Capital of Western Australia) on the west coast, and just coming into our summer. We have a hot dry climate in summer and cool wet winter, in fact our seasons are very definate.
Hope you can help
