My 7 mo. old serama hen hasn't been herself lately. She usually jumps out of the cage to run around and is very perky. She's been less energetic and not wanting to come out. Today, she layed her second bloody egg. I also noticed she had really watery droppings today. I keep the seramas in a small coop in the house. The floor is wire grate, no bedding. They're on flock grower with oyster shell and grit, along with veggies as treats. Anyone have any ideas?
