Lucy is a red star that just turned three last week. She's been looking a little off lately, very lethargic, not her usual self. She seems to not be able to hold herself up very well and falls every once in a while. The other chickens have been ganging up on her and attacking her. Is there anything that can be done? They have quite a bit of space in their coop and run, but should Lucy be separated from the rest of the chickens for the time being?
