What age do you ring your youngsters? We have done it at 5 days as recommended but have found them coming off them sometimes. And if we wait longer we cannot get the rings on
We like to ring the ones in the cotes, they are harder to log dates and times unlike the lofts, we do not always get the 5 days right.
I was very surprised to hear you can or some can, ring them up to 17 days if they know what they are doing
