Aberhall Farm is a large chicken farm, comprising of six sheds heated with warm water underfloor heating and hot water overhead heaters. Creating this heat are six 200kW biomass boilers, with LPG back-up. Each boiler earns between £20,000 and £25,000 in RHI payments per year.
Biomass creates an indirect, dry heat that has the potential to greatly improve the chicken’s Feed Conversion Ratio (FCR). The space in which the birds inhabit is also more uniform, with heat distributed evenly and litter noticeably drier and more friable. All this adds up to healthier chickens; mortality is much lower, ammonia levels are reduced and there are fewer cases of common barn hen health problems, such as hock burn and footpad dermatitis.
