I have just got my first ever chickens, they are about 16-20 weeks old. I have a few questions 1. Do I need to treat them for lice preventably and if they have lice what do I look for? 2. Same question about worms do I treat to prevent and what do I look for if they have them and 3. Do I need to vaccinate them and if I do is it an annual vaccinations
Thanks
Thanks
