How many chickens are on 1/4 acre?

I'm curious, could you provide me with an estimation on how many chickens could comfortably fit on a quarter-acre plot of land? Are there any factors that should be taken into consideration when determining this number, such as the size and breed of the chickens, or the availability of food and water? Understanding the potential capacity of this space would be invaluable for anyone looking to start a small-scale poultry farm or simply keep chickens for personal use.
