“Manure quantity and characteristics are influenced by the spe- cies, age, diet and health of the birds and by farm management practices. Estimates of the manure excreted by 1 000 birds per day (based on average daily live weights during the birds’ produc- tion cycle) are approximately 120 kg for layer chickens, 80 kg for meat chickens, 200 to 350 kg for turkeys (grower females and grower heavy males, respectively), and 150 kg for ducks (Collins et al., 1999; Williams, Barker and Sims, 1999). Extrapolations can be calculated to give general estimates for the number of birds in a given operation.”

It depends on many aspects including whether it is a layer bird or meat bird, diet and age. I’d estimate between 2500-3000 layer chickens as an example.
