Hello everyone. One of my hens, about 3 years old, has been acting funny today. She was fine last night when she went to roost but didn't come out this morning. When I got home from work she was still on the roost! This is very unusual for her. I picked her up and set her out of the roost. She didn't move much at first but after about 10 minutes walked over and took some drinks out of a puddle. She didn't walk around and peck with the other girls so after a half hour or so I quarantined her in a dog kennel in the garage. She still isn't doing much. I have observed her drinking water but not eating anything. She seems like she is panting. We did check for a bound egg but didn't feel anything. She has not laid a egg in at least a month (due to stress from introducing new ones this summer I think). Any thoughts, suggestions, advice? Thanks in advance.
