I came home this evening to everyone panting. My RIR hen was on the ground. She was panting the worst and couldn't stand for very long. She will stand, but sometimes balance herself with her wing. I brought her in and let her cool down. I offered her some feed and water. I had to dip her beak in the water, but she went nuts over the feed and ate hardily. She seems to be 'double swallowing' when she eats as well. Doesn't feel like anything is stuck in her crop. She still isn't standing too well. What do you think this could be? Heat stroke? An effect from the Sulmet treatment just finished? I just want to know if I should be doing something for her. Thanks!
