the place to chech in the genetic code page, which is part of the
taxonomy page at the NCBI.
On checking there I do NOT see any GTA start for chicken
(The standard code), just some alternative CUG and UUG (Leu in both
cases), but maybe checking with folks at NCBI would help.
Looking atthe CUG/UUG papers could maybe help you figure out
what they did to find these alternative start codons.
Hope this helps, cheers,
