Some of my hens have gotten too fat, even though they are pastured and I feed a good quality organic feed and not too many treats. The fat ones are mostly 2 !/2 yrs old. I have the ability to separate them for the winter and put them on a reducing diet, since their only feed will be what I give them during this season. Any suggestions on how much to feed or what to feed my fatties? I don't think they're laying well, so it's lose and lay or I'll have to consider culling. I just can't afford to feed fat hens that don't lay.
