Lots of people have been asking what the ring on there African Greys leg means so i will try and put it basic easy terms...
Most normal rings look something like this... 1 ABC 08 V
1 = The number of the chick the breeder has hatched either that year or in total
ABC = The Breeders initials or letters that links o them
08 = The year the baby was hatched
V = The ring size
Some rings might look different like this - MCA 12.99
MCA = Stands for the Aviary
12. = Is the Number bird that was bred
99 = The Year
Imported birds tend to have split rings with nothing on and so do breeding birds which also is used for sexing, a male or female depending what leg it is on!
Hope that helps
