Pasture-based chickens require 1.5 square feet per bird, so a Salatin-style tractor could hold 80 birds, while a Suscovich-style tractor would hold 36. However, chicken tractor design comes in many forms and is only limited by your imagination. Two popular versions are the Salatin-style 2 tractor which is a short cage approximately 10' wide, 12' long, and 2' high and the taller A-frame Jon Suscovich-style 3 tractor which is approximately 5.5' wide, 10' long, and 5.5' tall. Chicken tractors come in many different styles.
ROCK CORNISH CHICKEN FREE
A chicken tractor is a small and mobile structure that shades the chickens from the sun, keeps them dry in the rain, provides a windbreak, and protects them from predators while allowing them free access to the pasture. Secondly, you will need a chicken tractor. You can learn more about brooders from the University of Maine Livestock website 1. Getting Started – what do you need?įirst, you will need a brooder set up to get the chicks started off on the right track. Slow growing birds have a lower dressing percentage of 67-69%. They also make a more appealing photograph for marketing opportunities. Producers often choose these breeds over Cornish Cross citing ethical concerns over Cornish Cross growing too quickly or they want hardier birds that survive on pasture better. These factors increase the cost of production. While they will consume approximately the same amount of feed, they will utilize more water than Cornish Cross birds. However, hey will grow much slower than Cornish Cross, and often take 2-3 weeks longer to reach the same size. These breeds appear to be more heat stress-tolerant. These birds have a fuller and much more attractive plumage. The most common include Freedom Rangers, Imperials, and Kosher Kings which are all derived from cross-breeding several heritage birds. Cornish Cross birds have a high dressing percentage of 75%.Īlternatively, there are slower-growing meat breeds that do not have the same issues as Cornish Cross.
ROCK CORNISH CHICKEN SKIN
This exposed skin can be susceptible to insects leaving their skin a bright red color. You will often see them with exposed skin towards their rear, belly, and underneath their wings. Cornish-cross chickens are unattractive white birds with spotty plumage. Raising these birds longer than that is an invitation for sudden death loss.
I would recommend harvesting these birds between 6-8 weeks of age. However, if the birds can grow too long (past 8 weeks) you may see issues with lameness due to their physical size, heat stress, and heart problems. These characteristics make the Cornish cross the most economical breed to raise. These birds have been genetically selected for rapid growth and feed efficiency. The most common broiler in the United States is the Cornish Cross, a hybrid of a commercial Cornish chicken and White Plymouth Rock chicken. Along the way, I hosted dozens of pasture poultry workshops to gather information from existing pasture poultry producers and share what we had learned raising poultry at the University of Maine teaching farm. The summer, the University of Maine started the Maine Pasture Poultry Project where we raised broilers on pasture and meticulously recorded feed intake, water intake, forage utilization, growth, carcass, and climate data to share with producers in New England. Unfortunately, science-based recommendations for raising poultry was all geared towards large-scale production or raising chickens in barns. When I first arrived in Maine in 2017, there was a tremendous amount of interest in folks wanting to raise pastured broilers, but I noticed there were quite a few misconceptions about raising chickens on pasture which lead to a great deal of confusion among new producers.
I serve as the lead investigator for the Maine Pasture Poultry Project and I raise pastured broilers at home on my farm. Knight, and I am the state livestock specialist and assistant extension professor for the University of Maine Cooperative Extension. The following article introduces him and detailes his recommendations for pastured broiler flocks. Knight was asked to contribute to Penn State Extension Small and Backyard Poultry Flock Programming with this article. Note: As a member of the New England Poultry Extension group, Dr.
