  • June 29th
    a fallen swift chick was brought to my house. I didn�t have any nests suitable to add it to because they were all younger. The nest I chose, box 7, to add it to contained three chicks about a week younger. Could a pair of swifts cope with 4 chicks?
    �
    Sorry for the lack of diary. Not much has been happening this year
