My cream legbar on left of photos is the oldest chicken I have and she has shrunk smaller than my younger legbar. Her wattles are pale and sagged over and it’s been like this for ages I’ve wormed them all and flead them but she hasn’t changed anything, also her neck feathers are really pointy now like they’ve fallen off and I’m not sure what to do. Is she going to die. Their food and water intake is good since the other chickens are thriving so I’m just worried
