After having been given 2 full-size Buff Orpington hens, I think I've managed to get most of their needs taken care of. Little things keep coming up, though, such as: they have a PVC feeder full of food available in their house at all times, but when I go outside in the afternoons they run over to me and obviously expect something. What could it be? Is there some other food I need to be giving them late in the day? Sometimes they act like this in the morning too, I wonder if the people who raised them had them used to some kind of treats. By the way, the feed in their cage is a laying mix from a feed store. People have told me they'll love food scraps, veggie leftovers, etc. These girls really aren't interested... I can throw a bunch of lettuce out for them and they check it out & walk away. Any advice? Thanks.
