I have had a few chickens a few times but nothing like i have managed to get my self into this time
. I have 80 pullets Barred rocks, RIR, Easter eggers, Red star and a few more pure bred breeds. 1/2 are 11 weeks and the other 1/2 are two weeks. my question is how old are they before i can put permanent leg bands on them so i can keep track of age and breed with out having to worry that they will grow out of them. thanks for your help
