Some hen's do seem to be picky for what brand they choose to eat
I don't know if it is down to different colour/size/shape as there can be slight differences between different makes.
It could also be that they simply don't need to eat as much..perharps this particular feed is more 'filling'. If you girls lay well and look and feel healthy there is no reason for you to change again. As long as they do eat.
Have they got more other food sources available?..perharps somebody has been treating/supplementing them with something else? Do they get more greens than before?
Have you got poultry grit available for them? Some feeds are more easily digestible for birds and with others they might need more grit to help it go down...in which case there is only so much room in their crop for food and seem that they don't eat as much.
What brand is the feed. My girls are on Spiller's (or something like that..can't remember without checking the bag) layers pellets and bag seem to last for ages compared to other brands that I've used in past.
