I suspect one of my hens has been laying internally. She stopped laying a couple years ago and has a firm, enlarged abdomen area along her body beneath her vent. This "lump" has fluctuated in size over time, sometimes diminishing to being very small, or sometimes feeling very large and lumpy... it differs over the course of several months. I am wondering if she has been laying internally and is just somehow able to absorb the eggs if she stops ovulating for a period of time? And maybe that would explain why the lump has grown and decreased multiple times over the past couple years? Is there any way to cause her to stop ovulating? I have thought about keeping her in dark for some time, Leupron (but expensive and I'm not sure if I can get it in my area), only offering enough food for maintenance. Are there any supplements/etc that would cause her to stop? Any other considerations on this problem or advice on other methods of treatment would be greatly appreciated. She is otherwise healthy besides having the large, rather heavy lump. Thanks!
