Before today, each week I used to catch some of the chicks, put them in a cardboard box and weigh them and record the average weight. Today I couldn't find the cardboard box. The chickens showed me a much easier way to weigh them. Less than 30 seconds after putting the scale down, a little rooster would jump up and weigh himself. I'd record his weight, shoo him off and wait for the next one to jump on. I weighed three of them today this way. The average weight of these White Rocks rooster chicks was 1 pound 5.7 ounces. They are 6 weeks old.
