I have 7 pullets that are about 23 weeks old. My black sexlink has a crippled foot and is very small; she looks like a 12-13 week old. She is extremely timid and doesn't mix with the flock, won't leave the coop without my help, and hides under the feeder, wheelbarrow, or just tries to tuck her head under a board in the pen or when free-ranging. A couple of the pullets just attack her relentlessly, adding to her trepidation. She is so terrified, I don't think she has any quality of life. Given her growth, I doubt she'll ever lay eggs, and will end up as a pet. I've considered putting her down, simply to alleviate her misery, but I really like her. Thoughts?
