My parents and I were out building a nice, big run for our flock since we've had so many predator problems recently. I noticed my bantam hen and her "baby" (who's now bigger than she is) standing nearby, but Mommy Hen was not acting right. I looked closer and the entire left side of her face was swollen and her comb and wattles were pale pink and scabby. I've had problems with yellow jackets attacking babies but never adult chickens, but I thought they might be part of the problem. I caught her up (which was WAY too easy) and brought her inside. I gave her a little benedryl to help with the swelling and separated her and her baby with plenty of food and water with electrolytes in it. I also gave them some yogurt. But that was yesterday ad she hasn't perked up at all. She's so droopy and sad looking. She did have a dog take her other baby a few days ago, so maybe she's depressed? But I know there's something else wrong too. Her poop is good and she's eating and drinking (though not enough). I'm keeping enough benedryl in her to keep the swelling down. Any ideas? How else can I help her? She's my best mommy (besides my silkie) and I don't want to lose her.
