Well, this morning it rained A LOT, and the run got muddy and it smelt like ammonia, so I had to move my tractor to a different spot... While I was doing that, I noticed my White Leghorn started making this really, high pitched sound, kind of like a bark, and she kept doing it... I will check for lice and mites, but is my hen sick? If so, what should I do with her? She is 19 weeks old no eggs, whats wrong?
