Hi Donna
The parents will show no negative behavior toward pinioned cygnets. Because pinioning should be conducted at 1-3 weeks of age by a licensed veterinarian, the procedure should be completed in a timely manner so that the cygnets are returned to the parents within 1-2 hours. The longer the cygnets are separated from the parents, the greater probability for rejection by the parents. There are wo possible methods to prevent rejection by the parents. One is to take the female swan to the veterinarian’s facility with the cygnets so the young birds are within sight of the parent. Second, is to have the veterinarian come to your site and have the cygnets pinioned and immediately returned to the parents once the procedure is completed and no bleeding is observed. The Regal Swan
