She was alive when Doug found her but all floppy and not at all well. We put her in a box in the spare room with some food and water but she died the next morning.
She was very thin and we don't know why. We couldn't find any mite or lice on her and Doug wormed them all only a few weeks ago. I feel bad that we didn't notice before. It is hard to see how fat they are without catching them and catching them is difficult - really only possible in the dead of night when they are sleeping. A few of the others seem quite thin, but there is often a little food left at the end of the day, so it doesn't seem we are under feeding them. We have been feeding them a bit of cat food (recommended way of giving then extra protein) and we will do a thorough inspection of the coops for any mite or lice. Worrying.
