Our 6 month old hen hasn’t laid for about 5 days now. She just started laying a few weeks ago, and we haven’t had any in awhile. She also has some greenish poop (pic below). They get to roam the backyard for about 1-2 hours a day, so I’m not sure that she’s eating enough green for that to be the issue, but I’m new to this so I don’t know. She’s otherwise acting perfectly normal. Any idea what could be the issue?
