I took in a hen that was being kept in poor conditions. Her comb and face are really pale and they seem really dry. Her comb is cracked in a couple places from being so dry. Is this an indicator of some kind? Her feathers are also pretty dull and tore up like she'd been picked on by a bully roo. I've sprayed her with poultry protector and giving her good feed (she was only on corn before) and I've been putting electrolytes in her water. Is there anything else I can do to help her comb?
