A dove who never touches a hanging toy is not a bird without curiosity. She is a ground feeder being offered enrichment at the wrong height. Doves walk, peck and sift at floor level, so every successful idea for this bird starts on the ground and stays there, arranged across the floor space she already trusts.
Build the Interest Into the Floor Itself
Scatter part of her daily seed through clean substrate spread in a defined area of the cage or aviary floor, so she has to pick and sift rather than eat from a full dish in one visit. A shallow forage tray does the same job in a tidier form: a flat tray holding a thin layer of substrate with seed, chopped greens and a few seed heads mixed through it. Keep the layer thin enough that she finds food steadily, because a tray where nothing turns up teaches her to ignore it.
Add a hay and straw tray alongside it, with short pieces she can sort, toss aside and pick through for stray seeds. Set a wide, shallow bath pan on the floor with water deep enough to splash in but easy to walk into and out of, and place it away from the main feeding scatter so the seed stays dry. Low platforms, just a small step up from the floor, give her a raised feeding spot without asking her to climb or fly to a perch toy: lay millet sprays flat on them, place chopped greens there, and let her hop up and down in her own time.
Rotate Textures While Everything Stays Low
Variety for a dove comes from what is underfoot, not from what dangles overhead. Change the forage tray's contents on a simple rotation: one day a layer of clean sand to sift, another day fresh grass turf cut from a spot you know is untreated, another day dry leaves or shredded paper over the hidden seed. Each change renews the same floor area, so she investigates the ground again rather than learning one tray and then ignoring it.
Move the bath pan and the hay tray to different floor corners when you clean, while keeping the overall layout familiar enough that she is not unsettled. Fresh seed heads and laid-flat sprays can appear on the low platforms as the novel item of the day, then be replaced before they go stale or soiled. Remove damp substrate, wet hay and bath water promptly, because ground-level enrichment sits where droppings also land, and a tray that smells stale will be avoided however interesting its contents look. Wash trays before refilling them rather than topping up over yesterday's layer.
Read What She Uses and Build on That
Watch which floor offerings hold her attention across several days. Some doves spend long stretches at the bath pan and only pick at a forage tray, while others work a hay tray methodically and bathe rarely. Let her preferences steer the rotation: give the favoured activity more floor space and more frequent refreshes, and retire the tray type she walks past untouched, replacing it with a different texture at the same low level.
Allow time out of the cage on a safe floor where that is practical, with a forage tray placed there too, so ground feeding is part of her wider day and not confined to one corner. Keep a brief note of what was offered each day and what she used, since the pattern is hard to judge from memory alone. In KinsLe you can use Care Teams to share the tray, bath and substrate changes between the people who help with her care, with a timestamp on each finished job, so the floor stays fresh even when the usual person is out.
