DEFRA.....
These are the rules
If your sheep loses its identifier or it becomes impossible to read, you must replace the
identifier:
• no later than 28 days after the tag was removed or discovered to be lost or illegible;
or
• before the sheep is moved from your holding;
whichever is earlier.
3.15 Replacements – general
Whenever you apply replacements you must make a record of this in the replacement
section of the holding register.
3.16 Replacement tags – double identified animals
The replacement rules are the same for full EID identified animals and those in the
historic flock.
a) Where one tag is lost
When you need to replace one lost tag you have the following two options.
Option 1
Apply a replacement tag which has the same identification number as the original tag,
and then make a record of the replacement in the replacement section of the holding
register.
I suggest this is the simple option
You would need to order a tag with the same number from your supplier. The tag must
not be red.
Option 2
Remove the remaining tag and apply a new set of identifiers from your stock of tags. If
the animal was identified after 31 December 2009 and kept for breeding or beyond 12
months of age, one of the identifiers must be electronic, and the following will apply.
Section three
19 Section three
• If the animal is not on the holding of birth, the replacement tags must be red (unless
identical numbered replacements are applied).
Your sheep have their ID tag so you already know their UK number so you do not need red!!!!
• If the animal was first identified before 31 December 2009, replacing with an EID
identifier is optional.
• You must cross reference the old number and the new number in the replacement
section of the holding register, except for older sheep still on the holding of birth,
when no cross reference is necessary.
No one needs to know they never had their EID tags in.....just put one in as a 'replacement'
