Went through all my first hatch while I was moving them to the grower cage, checked for any thing health wise and checked their zip tie leg ring for size. After much struggle with the first one that needed replaced, i ended cutting through the little block with a set of jewlers dikes ond it popped right off. Just noting this because I think some one was on here needing to know how to remove them. The first ones were put on at 5 days old, they are now 21 days old and some were getting ready to cut off circulation. Which shows if you use leg bands you have to be on the ball. If I had waited just 2 days more there might have been problems. Fortunetly no injuries.
