makes you wonder when the result says 401 birds from 520 marked so that makes 119 birds still missing how do they go wrong when they are all going to the same loft ????
i use the orange one on my birds do 2 large dots on the top of wings looks like a pair of hark eyes when wings are open and flying i get mine from agricultural outlets ie scats countrywide (others are avalible ) and its only a fiver a tin .
should of looked here before ringing about my bird reported in holland may have helped as the bloke spoke no english and his wife only spoke very little spent 30 mins to get everything sorted with them repeating over and over again
the thing is where ever you go wheather taking 20 birds or 1000 birds bop seem to appear from no where i got 30 young birds and train all times of day to avoid bop but sometimes they come together and other times they are split you cant blame the loft manager or any indervidual who tries to train pigeons if bop is hungry they will hit on lib or on the way home .
unless farmers get some rain in the next 10 days wheat will go up again next year we are looking at a poor harvest unless we get some rain as the plants are not getting the nitrogen into the leaves .
i know you can get ones for chicken houses that open at 30 mins after daybreak and shut 30 mins after dark weather these can be changed to suit you i dont know but its something you could look into just found them they do a timer version too http://www.chicken-house.co.uk/acatalog/Automatic_Door_Openers.html?gclid=COfV7PSNzqcCFQoZ4QoduAHyCw
