My girls just started laying and I switched them over from purina flock raiser crumbles to the layena pellets. It's been in the feeder for a few days now and they don't seem to be very interested in it at all - it seems hardly eaten. The weather has been really cold here the past few days too, so I can't really figure it out. With the crumbles, I was refilling the feeder about every day and a half. The layena has been sitting there for days. Do you think it could have anything to do with the change from crumbles to pellets? My first thought was if they're hungry enough, they'll eat. But when it was still sitting there today I was a little worried. What should I do?
