Give them more protein when they are molting. It takes a lot of energy to grow feathers. Hot temperatures almost always stresses them and egg products slows. Any stress will cause a loss in egg production. I will give extra vitamins in times of stress. I put vinegar in their water. Make sure...
When using oral wormer check for with draw times. That when you don’t want to use their eggs. Either throw them out or hatch them out. Some people say they eat them anyways but I wouldn’t.
