There are lots of stray cats in the neighborhood so we have been leaving out food and water every morning for them. About a year ago, we noticed a stray hen that comes almost everyday to eat and drink too. We didn't think too much of it, and thought that the hen must be from a neighbor's coop and just out adventuring in the day time. One night we heard her making noise around midnight in the backyard so i followed her and she flew up to a neighbor's tree and I couldn't see her after that, since that tree is in a gated front yard. I thought maybe she was out having too much fun and the coop is now closed so she had to sleep outside for a night. Fast forward to about a month ago, we found that the hen started laying eggs in our backyard. So each morning she would lay an egg in the same area and in the evening she does not sleep there. We decided to take all but one egg behind each day so that she sees it's still there. So she comes back everyday and lays another. 3 days ago, we noticed that she's now just laying on top of where she lays the eggs and doesn't seem to have moved at all. I tried to place food and water near by and she does not seem to be eating. Is she trying to hatch eggs? or is she sick and trying to die there?
