Here on Farming Today we've been reporting on the rising costs farmers and food producers are facing. Now, British free range egg producers have said that without substantial price rises of 40 pence per dozen eggs, farmers will not be able to afford to keep their free range hens due to feed and fuel costs having risen so much, and have invited major retailers to a 'crisis summit'. The Environment, Food and Rural Affairs Select Committee has chosen Labour MP Geraint Davies as its' interim chair, and says a new substantive Chair will be voted in, "in due course". The horseshoe bat has seen a decline in its population in the twentieth century, which some attribute to intensive agricultural practices and others to roost disturbance. However, there are signs the population is now on the increase. And this week we're looking at spring vegetables, and today we're talking Scottish asparagus.
