Hi - new chicken owner here and have my first hen that’s not acting normal. She’s a 6 month old Barred Rock who is usually super curious, active and pecking my ankles for food. Two days ago I noticed she wasn’t moving as fast, puffed up, and not her normal self. I thought maybe egg bound since she hadn’t started laying yet. She’s been drinking and eating on her own. Today, getting the coop ready for winter, we saw her lay her first egg in the run. After she laid she came out to free range in the backyard like normal. First poop we saw from her after egg was laid was super watery, white foamy with a tinge of green (see picture). She did eat arugula yesterday. She eats organic layer pellets. Now she’s back in the coop run just standing in one place. She’s usually the last one in when they get to free range. Any suggestions for me? We have 6 other hens of different breeds who are all acting fine and normal. Thank you!
