I opened the chicken door this morning and the stampede was not there. How weird, I thought. I go to the people door and immediately see Opal curled up in a ball in the corner. When I put them down for the night, she was on the roost. Yesterday, she was scratching and dust bathing with all of the girls. No one has been sick. The only difference in the coop is my hubby put in new roosts, which are a little too high in my opinion. Should we install a ladder for them? or reinstall them lower? Also I put my 11 week old EE Roo in there, but that was after dark to introduce him. She did not have a mark on her. She had her head tucked under her wing, like she died in her sleep.
