Does "CpGs rule" apply for chicken?

[Matthieu Vermeren (Anatomy)]

We are currently trying to design a "guessmere" to be used for screening 
a chicken cDNA library. The references we have, unfortunately, apply to 
mammals. They suggest, after using the preferred most-frequent codon, to 
account for the relative infrequency of CpGs. Does this rule also apply 
for chicken? Do you have any other tips that may help?

Thanks in advance
