Are those zip ties for ID's? What a good idea...how do you know how big to make them when they are chicks? Do you just keep cutting them off as they get bigger?
Yes the zip ties make a quick and easy way to identify each chick for record keeping. I get the weight of each chick weekly. As I am doing this, I check to see if the tie is ok. If not, I replace it with another tie. When they reach maturity I will replace the tie with a proper leg band.
