My Fil has chickens. He breeds them, i.e. hatches out the new ones and eventually sends the old ones to chicken heaven. The new chickens aren't vaccinated against anything, they are just hatched and obviously then lay their own eggs which he sells to people in the village and sends down to us. Not sure if chickens need vaccinations but I am sure I've read on egg boxes before 'these chicken's are vaccinated against blah blah blah' Firstly I don't really like the idea of eating spermulated eggs (there are cockerels in with the chickens), but my main question is 'Are these eggs safe to eat when I am pregnant if the hens haven't been vaccinated against chicken ailments?'
