I have an approximately 15 month old Cuckoo Maran. She didn't get off the roost this morning (roosting in the run). I took her off and put her in the yard. She didn't want to walk around much. Didn't want to scratch. Only saw her peck at some grass once or twice. No problems standing. Color looks ok. She did go back to the run, take a few drinks and fly up on the roost around dusk. Sounds like she does have some congestion. We took her out of the run and have her in a crate in the house. Haven't seen a poop yet. I think she last laid two days ago. Other hens seem fine. Suggestions?
