We are at week three on one farm. This bird should weigh about 1.8 pounds at this point. In my opinion birds this size start going through the ugly duckling stage. They have lost most of the fuzz and are putting on feathers. The house temp is kept around the upper 70’s.
On another one of our farms, the birds are 4 weeks old. This bird should weigh about 2.9 pounds. As always, his environment is close to perfect to keep him healthy and growing well. I don’t know the actual calories per day they are getting from the feed, but I’m assuming it would be like a rib eye and baked potato plus a chocolate cake three times a day for us. That may be a stretch, but they are getting all they want any time of the day except at night when they are asleep.
