Our white holland female that is a year old has developed a large swelling right in the middle of her breast. It isn't hard at all and it doesn't seem to have anything in it, it's more like a flap of skin like might be around a crop but it's all the way down in the middle of her breast. It just appeared today. She's not acting ill or anything and is happily eating and running around like normal. It's been really hot though and she's been laying in the shade and then getting herself misted every once in a while to stay wet. Could it have something to do with that? We've also had a LOT of wasps and things lately. Is it possible she could have been stung by something and if so what do we do about it? Like I said it doesn't seem to be bothering her at all. I'll try to get a pic of it tomorrow and post it if she doesn't keep laying down on me.
