I got 6-SS. They used to LOVE to eat pretty much anything. Love the feed, love the grass, bugs and treats. But in this few day, they are not eating. They come out from coop and scratching ground. They come to me to get treat. But feeder is not going down. I checked their crop every night. They are not hard like used to. Soft like water ball. When I go out with feed with container, they used to eat from container. But now, they eat only when I hand fed them. I didn't change feed, it's same company and same bag. Only thing changed is... one of my hen got killed by hawk (or falcon) last Saturday. It happened front of them. Do you think they are still in shock??? Or something going on???
