Sad to deal with. Thank youI'm sorry you're in the same boat. Our blind-ish hen (we named her Ground Layer for obvious reasons) has always been able to find food, water, grit, and oyster shell, but I think when we enlarged our flock, so grew too timid to go after food and water for fear of being pecked. None of our birds are aggressive, but when she bumps into them they take it as an affront.
Sorry for your issue also
