I did a google - found this - no answers though.
Our chickens are fenced in a largish area with a flexible mesh fence. Yesterday afternoon, I discovered one of the dogs (a black lab who eats everything) in the fenced area.
He had polished off half of an Omlet "peanut" feeder of layers pellets.
He was bloated and unhappy.
So far he has been sick three times, and had extremely pungent copious diarrhoea five times.
Thank goodness we have tiled floors and no carpets.
I have no idea what is in layers pellets, but it disagrees badly with labradors.
We are starving him until this afternoon and then he'll be on boiled rice and yogurt for 24 hours to attempt to soothe and recolonise his gut.
