I have four hens, three haven't started laying yet and the other is just finished molting. We used to have only two, but then one(named Christina) died of sour crop. The original chicken that didn't die was a little more skittish than Christina,but was overall friendly. She saw Christina die and ever since then is terrified of us, and if she sees us she'll run away screaming at the top of her lungs. When we got our new chickens, she taught this to them, so now we have 4 very unfriendly chickens on our hands. I know they're not supposed to remember, but she remembers! So, does anyone have tips on making chickens more friendly?
