I have thought about quails too but the garage that would be ideal as it has a concrete floor, is going to be used for something else, my daughter had some but they died/ were killed, she loved them and would have more but they are in Leicestershire, her partners dad used to breed them in India, years ago!!! Hard to admit to yourself some things change as we age, I know that feeling, I worry too about things going wrong with me, my legs still keep going weak, have had an X Ray and off to get results tomorrow......anyway, you do work very very hard so a bit less work and a bit more fun should help!!
