Just to explain a little on the above,while my hens raced twice a week they were fed 1/3 sup/diet 1/3 wid/mix 1/3 yb/mix to replace muscle tissue.If only racing once a week and no training,they had light food from the sunday until later in the week,then fed a good wid.mix.On return sat. they were fed diet/wid/yb.
