Curious, in your practical experience, do your Cornish X follow the Welp weight chart generally? Mine are not Welp, but they're a little behind--they're 3 weeks and 4 days but weighing at the Welp 3 week mark (around 1.8 average). But, they're not Welp and I know that Welp is kinda the gold standard. Plus it's been cool and I imagine they're burning some to stay warm. Since this is my first time doing this, I'd rather be on the safe side and have them weigh a little less than develop issues. They seem to be staying pretty active. Is 1.8 lbs decent for 3.5 weeks?
