Hi there, just wondering if anyone has any ideas on stopping an older hen from trying to lay? I have an old dorking that still tries to lay however the eggs either had little or no shell. I just finished treating her for egg peritonitis and she is doing well but I noticed she is in the nesting box again. This morning the hens were eating an egg that probably came from her. Topical estrogen? Any other ideas? No chicken vets in my area either.
