In every feed store, you’ll find bags of grit and oyster shell near the chicken feed. Why is that, and what exactly do chickens need them for? Learn from Nutrena poultry expert Twain Lockhart what the benefits of them are, and how you should feed them to your flock.
Oyster shell and grit are not interchangeable
Oyster shell supplements the calcium in chicken feed
Grit aids in digestion of grain, plant materials, bugs, etc. – when in doubt, put it out!
Timing is everything when it comes to feeding your laying hens. Ensuring they have the correct nutrition at just the right time is an important part of having a happy and healthy flock.
Hatch to approximately week 6: Provide free choice access to a quality chick starter ration and make fresh clean water available at all times. Proper nutrition in this critical growth stage will impact the performance of the chicken for their entire lifespan. Use a heat lamp to keep birds warm and provide 1 sq. foot per chick.
Approximately 6 weeks to 16 weeks: Continue to provide free choice access to chick starter and water. If you choose to feed treats (scratch grains, kitchen scraps, etc.), put out what birds will consume in about 15 minutes once per day. This a good guide to follow to make sure treats don’t exceed 15% of the total diet. Add treats only after week 6. If birds have access to anything other than a crumble or pellet, provide grit free choice in a seperate feeder.
16 weeks +: Now is the time to switch to layer feed! Provide layer pellets or layer crumbles and grit free choice along with access to fresh clean water at all times. Treats can be provided at no more than 15% of the diet. At this point it is also important to make oyster shell available free choice to provide supplemental calcium for hard-shelled eggs. Adult birds require approximately 3-4 sq. feet of space per bird in the coop; you also need to plan on one nesting box for every 4-5 hens.
