My house duck, a fawn & white runner named Olive, hasn't been laying super long (started 08/13) and she is already a chronic problem layer. We've encountered egg binding and yolk loose in the oviduct (luckily not the abdomen) multiple times, and she lays incredibly often. She lays massive double yolkers (shelled) very frequently, often times twice a week. Her regular eggs are bigger than her head already as it is and she has knicked her poor vent on them twice now. We've been working with our vet to treat these issues as they come but at this point it seems fairly obvious that we're playing with fire here and we need to take a preventative route or one of these times something is going to happen and we won't be able to fix it. We got her two hormonal implants today that will hopefully shut her down but there is no guarantee. On top of that we were asked to remove anything she is sexually attracted to, stop petting her back (luckily doesn't happen much already,) and to shorten her photo-period. He especially wanted us to try to get her brooding. She won't lay while nesting or raising young, and brooding/mothering is apparently a progesterone thing so it won't be altered by the implants (which is dealing with estrogen.) I know that I need to let her keep a nest of eggs rather than taking them from her and that is about it! She has never shown interest in going broody and I have never had a broody duck before. I did explain her breed is one known for being disinclined sitters. He suggested she might adopt if presented with ducklings and switch right in to momma mode if we really can't get her to brood, but I'm not super keen. Is there anything I can do to to further encourage brooding? Getting her a boyfriend is a definite no-no. Other than that and giving her a super nice extra soft nesting spot I haven't got any ideas. The last resort if none of this does it is a preventative hysterectomy and that is a HUGE risk, I want to exhaust everything else before considering it. Sorry to be so verbose but hopefully the details will help someone else. Please don't suggest culling. If it isn't obvious already, she is our pet!
