No.
This practice was adopted by factory farms to deal with the constant filth and disease that is their chicken filled warehouses. They will typically treat healthy hens with antibiotics as a prophylactic measure.
Our barns are airy, uncrowded, clean and safe. If in the rare circumstance a hen is discovered to have a health issue requiring antibiotics, and this is very rare, she will be segregated from the main flock and treated. Her eggs will not go into our cartons until she is fully recovered and off any medications.
