Hello,Hi @pspatbyc !My ex-battery Isa Brown hen, Chickie, is three years old and started showing signs of egg production problems, which usually leads to egg yolk peritonitis and death. I thought long and hard about it but got my vet to insert a Suprelorin implant into her. Made for male dogs to reduce hormone-related aggression, you can also implant it into hens to stop their egg cycle. But where you get 12 months effectiveness for a dog, you only get 6-10 months for a
hen. They are several hundred dollars each and you may need at least two. @micstrachan has also had experience with them.
Sorry about Chickie! (We hang out together on another thread, but U’ll answer tmhers.) Yes, I have found the implants very effective.. I currently have a hen on her second one and she is doing great! She has lost the bloat in her abdomen and seems to feel good. However, it dig trigger a light molt. Good luck and let hs know what you decids.
