I have had my first flock of girls for a few months , 3 BR and 3 BO. (i'm not sure that 6 chickens count as a flock but oh well.) They have been great. My question is besides clean water, feed, and shelter are there any basic needs I am missing? Do they need vaccinations, worming, check ups, ....??They get plenty of treats. Is there anything I shouldn't give them? They free range 12 hours a day. Thanks in advance for your knowledge.
