We bought six white pigeons about five weeks ago. Put them in the doocot, but wired off their escape route. They seemed content as we fed and watered them for about five weeks.
We thought that would be sufficient time for them to lose their homing instinct for Rosyth. So we took down the wire mesh. For a morning they posed around on the doocot roof looking cute then took off.
They have never come back to roost in the doocot. However we see them flying together and landing on neighbours roofs. They seem to be hanging out with seagulls too.
Will they ever come back?
