that is great i aint up to letting them let them out yet but when i am in the loft they follow me in and love messing with the babbies which i dont mind as it helps to get the babbies tame,
It gives me some great memories seeing the kids like that as i was just the same and have always been intrested in to them, and having some great memorries of the birds while i was growing up, my dad says when i was 6 i wondered off when we were on holiday in great yarmouth, and he found me among pigeons, feeding the street birds, (true story).
If your son is like me he will never grow out of the colours, because i havent you only need to see my birds at my house.
