My Blue Copper Maran started laying only a few weeks ago. She is approximately 8 months old. She hasn't layer an egg since mid last week. The last 4 days she has been isolating herself from the flock. This morning I noticed that she had an excess of poop matted up around her vent. I cleaned her up and I could see that her vent appeared to be slightly protruding, or maybe just a little puffy. The poop seemed to be unusually green. Also her comb is getting floppies than normal. What could be the problem?
