A bear attacked my 6 chickens back in July, ate 4. Two were left. My BR, age almost 2, is still traumatized. She lost her sister and hasn't layed proper eggs since. Her eggs are soft shell and broken sometimes on the floor. She used to lay every day, now only about twice a week. Her diet is the same except I'm giving her oyster shells thinking it will help--so far it hasn't. My question is how can I get her spirits back to normal? We have incorporated 4 more chickens and she seems to be okay with them, but she and her sister were always together. Maybe she saw the bear attacking her sister? Any thing I can do? Thank you guys.
