Roe deer fawns are highly vulnerable during their first weeks when does leave them hidden while foraging, and human disturbance or agricultural operations frequently cause injury or abandonment.
Roe deer fawns found alone during May and June are almost certainly not abandoned. Their instinct to lie motionless is their primary survival strategy. Human interference that removes apparently lone fawns creates welfare harms through stress, inappropriate nutrition in human care, and reduced chance of return to natural rearing. Genuine welfare action involves leaving fawns alone, watching from a distance for the mother's return, and only contacting a rehabilitator if the fawn is clearly injured.
