My one female Khaki who is going on two years old appears to be molting and is most noticeably losing the wing feathers. Today I noticed blood on one of the wings. Should I be concerned? Should I keep her separate from the others at night? Should I feed her anything special? She has also stopped laying eggs. It has been 18 months since she started laying almost every day so her eggs are greatly missed but I figured this is normal during molt. How long can I expect the molt to take? There are two males and one other female that are her babies (born last summer and now grown). They sometimes bully her a bit but nothing too serious as far as I can tell during the day. I appreciate any advice.
