I feel really bad for Lucy. She is constantly picked on. She is much smaller than the other birds. Idk what to do. We have more than enough room in the run and we even let them out in our yard during the day. She is ALWAYS on high alert. I checked on them last night and she was on the bottom roost. We have 3 total. What can I do to help her be picked on less? We have 3 black sex links and 1 other barred rock. She is laying but eggs are tiny.
