Black Brown Bantam hen, unknown age. She was fine when all the chickens got breakfast about 2 hours later i went out and she was just standing in one spot. She had labored breathing, eyes closed but not crusted, drooping head and wings, wattles were shriveled and purple. I brought her in and quarintined(sp?) her, gave her water and some tlc and she started acting better raising her head and opening her eyes. Well we kept her in for the night and the next morning there was an egg and it was HUGE! sorry no pics the shell was thin and it cracked. But i'd say it was about the size of a medium to large standard chicken egg. Ever since she laid the egg she has been fine. Any ideas?
