Hello We are new to this forum but have looked after a few chickens for several years now. We have a dark dorking with a huge swelling in the area beneath her vent, all the feathers have fallen out and it is the size of a cricket ball and quite heavy. However she is eating, running around and it generally seems to not bother her at the moment. She is a young hen, only just starting to lay but of course not at the moment. Has anyone seen anything like this before please? is it likely to be a tumour? I imagine there is nothing we can do but hoping someone may be able to help.
