I have about 35 eggs in the bator, I have some cuckoo marans from a well known breeder of them. He marked the eggs with a number of the hen that layed them. I would like to be able to put something on the chicks with their own number and keep documentation. I thought about using something like they use on quail. But chicks grow so fast, and I dont want to hurt them. Any ideas would be greatly appreciated!
