I feel so sad for you and your sweet chicken but because you shared so much about her and everyone offered their best advise I some how feel sad for all of us. We all lost your lovely little silke mommy and all wanted her to get better. Peace be with you and do share your adventures with your flock
I have no idea what you should do, but I did want to commend you for doing all that you are for her. I will give the floor back to those who know how to help. Good luck to you both
