Do I need to de worm my pigeons? I have never treated my pigeons with any medication... only ACV in the water sometimes for health. I just noticed that a few of this years young birds have grown up to be much smaller than their parents. Should I de worm my pigeons.... and also some have young in the nest... is it safe to de worm the flock when they are breeding? Also do you recommend I treat for coccidiosis too? I have always prided myself on keeping my birds natural as I can and not having to medicated... but over the last few weeks I have been having problems with my chicken flock with worms and possible coccidiosis... so its got me paranoid about diseases now!!! Thanks.
