My 11 week old buff orpington pullet has started acted differently today. She usually sticks pretty close with my 11 week old lavender orpington cockerel. So today she would follow him around and just lay down and fall asleep on her side when he would stop walking. When he got too far, she would go to where he is and lay down again. She has slept most the day today, whether it be outside in the sun, in the shade, or in the coop. Like usual, my lavender orpington has stayed close to her, but today when I go to check on her, he's being pretty protective of her and even pecked me once when I went to pick her up. Usually he is super friendly. She has been eating, drinking, dust bathing, and eating dirt and bugs as usual. However, she has been moving a bit more slowly, laying around a lot, and sleeping often. Her poop looks normal, it has a good white cap on it. Anybody have any ideas? I have no idea what to do for her or what is going on with her.
