HC Deb 10 June 1959 vol 606 c106W
Sir A. Bossom

asked the Secretary of State for Air if he will give instructions, when Government manœuvres are taking place in which low-flying helicopters participate, that they be particularly cautioned against the scaring of chickens, thereby creating unfertility in the eggs, since low-flying has in recent times caused more than double the normal unfertility.

Mr. Ward

I am arranging for R.A.F. helicopter units to be reminded of the importance of avoiding disturbance to chicken farms wherever this is possible.
