Work extremely didactic and practical, in that it classifies by type of use proposed models, he details the materials, and the icing on the cake, the budget nécessaire.Livre even more topical than the tendency to reduce the volume of waste - at least organic, is to appeal to these kind gallinacés.Un number of municipalities or intermunicipal through times like home, the déchèteries service offered to host this use a variable number of birds, free or for a fee (eg 15 euros a pair of hens Barbezieux race that almost disappear) .To do this, a makeshift barn or HAD hoc, if necessary, and I have not convinced by those available in DIY stores often well designed but poorly executed, poorly finished in brittle materials, and far too chers.Or I remember it as a "citizen" approach (as they say now for a little anything) that is part of a research development durable.En clear: it is our waste being asked to be biodegradable, not these barns! Remember: there is no need for a cock that research - besides processing its garbage - as eggs, not greasy poussins.La morning without crowing is saved, without seeking a quarrel with the national emblem which, remember it anyway just a bad game of Roman word, the word gallus besides Latin cock, wanting also say Gaulois.Pour memory, our war signs, the famous trumpets were shaped boar, no cock!
