Yesterday our Vet came out for annual ranch check and shots. When she finished outside and came in to work on the dogs she saw the chicks and said "Wow they look great how old are 6 or 7 weeks". They are turning 4 weeks old this Sunday. I wanted to use all the great info I've pick up here over the last 2 years to see the difference. After the first week they have been getting ACV in their water, a little ground flax in their food, and everyother day they get yogurt mixed with dry food. The fence went up around their brooder much sooner as they were getting very close to flying out. THank you all for the great info I couldn't be happier with the results!!!
