Hi, today we discovered a pigeon sat on our apartment balcony. It has been there now for around four hours sat on a edge of a plant pot.It did not move when we went out and it tried to fly away but flapped its wings and fell back down. We have put out water which it has drunk a bit of and bread .When it has opened its bowles it was quite slimy whichi think means its sick?? Does anyone know what I can do to help it ? I cant take it indoors as I have a small child does anyone know if anyone would come and collect it to treat it like a rescue cetre? we are on the borders of se london/kent.
