Hi, Our chickens are about 14 weeks old now and they are still skinny & flat looking. Shouldn't they be shiny fat & fluffy by now and if not when do they start? They have their regular feed and then lots of veggies & fruits scraps & such. We also let them free range for about an hour before bed time. That's about the only time we can. We also give them some mealworms once in a while. I'd think with all of that food & treat at their disposal they would definitely be fat by now.
