I have to agree with Sonoran. That is really heavy for 3 months old. Mine hardly weigh much at all at that age.At three months old they are both WAY too large for the standard. 36 oz is for a cock--a male over a year old. Cockerels should weigh in at 32 oz, but that would be a nearly grown cockerel, not a 3 month old. At least 6 months and probably closer to 8 or 10 months.
