I have a large black orpington hen I bought last Autumn at auction so dont know her exact age but she looks to be a year old or so,She laid last year and stopped when the cold weather came in.I have noticed she has started to act strange,she sits on her own and when I let her out she makes for the compost heap and scratches about then makes herself comfy,when I approach she doesnt move unlike before when she would scuttle away,When I pick her up to put her back in the run she starfts to (it almost looks like she is walking on the spot with high steps then she sits down in a submissive pose) Is this normal and what does it mean,I havnt seen it before,
