Just curious - I have been raising part-time backyard chickens for about 2-3 years now. Had to stop a few months due to relocating. Now I have 18 baby chicks that are 3 weeks old today. On a side note - ordered them from Welp Hatchery and so far we have had a great experience. Now to the yogurt. I just now read today that chickens love yogurt. My questions (although they may sound stupid) are: how old do they need to be before I start treating them to yogurt and does it matter what flavor? Thanks in advance for any replies.
