Hi everyone I have a flock of 16 Japanese quails. I keep them in 4 separate pens. In each pen there are 3 females with one male. They live on wire. Yesterday I noticed one of my females was sleeping all the time while she had fluffed up her feathers. When I poke her she wakes up and turns her head like when they are cleaning feathers of their chest and then goes to sleep! Every time I poke her she does the same thing. I put her in a separate cage alone. I tired to get her to drink some water. I had seen quail with injured head doing crazy things but this one seems very strange. What should I do to her? Is it head injury or some other disease? Thanks Mehdi P.S. : The bird is not a newly introduced one. And none of my birds have been sick these days.
