Opened the nest box to check on progress this morning and it looks as though things are going well. They are about a week old now, should be leaving the nest around 6-7 May.
Steps to move the bird's nest: the first is to locate the nest you want to move. Next is to use disinfectant and spray on the nest. Gently remove the nest and move it to another nearby location. Once removed, use a disinfectant or bleach solution and clean the area thoroughly.
