She may do well through molt. A lot of hens stop ovulating during molt, so this may actually give her a little better chance to heal.Yes I found some today. Weird that she’s sick and molting. I guess I just figured she’d be putting all her energy into feeling better.
But, I've also had hens have a bit of trouble once molt is over and they begin to come back into lay. It's one of those time will tell things I suppose.
