The clocks were brought back in line with GMT at the end of summer in 1945. In 1947, due to severe fuel shortages, clocks were advanced by one hour on two occasions during the spring, and put back by one hour on two occasions during the autumn, meaning that Britain was back on BDST during that summer.
Best Answer: 30 days I love pigeons, I have hundreds of them. First egg hatches after 30 days then the second egg follows next day. When both chicks comes out, the first one gets more feed from the parents as he is big and he reaches first.he incubation period for common pigeons is 17 to 19 days. The female sits on the egg from late afternoon through the night until about 10AM. The male then takes over and does the day shift. Once the eggs hatch, both parents feed the young squabs.
The chicks take 14 to 25 days in the nest, where both male and female doves collaborate in feeding them. In the initial stages of incubation, both birds produce pigeon milk, a milk-like substance, from the surrounding plants to feed the nestlings.
