i just read that robert whatever his name is link and man it made my blood boil!! i am one of the european chicken farmers he talks about! and he is talking utter rubish and in the most generalised way.
so a few facts about european farms and chcikens per acre. for a start most farms use a ratio less than 400 hens per acre even tho this is the permitted level. mainly we use less as a way to manage parasite burden, secondly he states the reason we have nice green grass is because we keep the hens indoors all the time, erm so he means instead of using the land in a productive manner we pay instead alot of money in fuel and time in just keeping the grass cut??? and have an increased feed bill??? NO NO NO NO. uterly and totaly wrong.
how we do it and keep nice grass is simple we use a ancient and mystical methos caled ROTATION!! now this is obviously not something he has ever come across so i will break the EU farmers code and divulge its secrets... we always have land in rest, normaly if i have heavy numbers per acre (300+) they will be on that acre for no more than 5 weeks then move them on, the acre is then turned over to 2-3 goats who clear up any stringy weeds or brambles or reed grass. the acre is then left for 3 weeks and turned over to ducks (normaly <200) then they are moved on and the acre is left for approx 8 weeks where upon sheep are grazed for a couple of weeks, then its a week off for the acre and chickens are added again, we do this to the acre for 3 years when it is then handed over to some weaners who totaly wreak havoc upon it and turn it into a swampy mess (idealy) we let that settle for a bit then hoe it with the tractor, at this point its normal practice to leave it for a year to 18 months in wich time we take a bedding haycrop off it every 6 months to "clean" any parasite load.
manure isnt a problem in a properly managed system, also the calculations dont take into account the reality of manure decomposting in the acre or things like flys laying eggs in it and the magots living off it, all of wich greatly reduce the real world amount of manure the acre would actualy have.
sorry to rant but i take offence at people posting in a knowledgeable way about something they are clearly guessing at. and i am not the exception of the UK farms, our own farm has fantastic pasture and our land is worth above average on the market, my family has farmed this land for well over 350 years exactly the same way as ive outlined.
