When do I switch my chicks from starter-grower feed to layer feed?

Some aspects of chicken keeping can be a little more of a guessing game, but the answer to this question is quite simple. 

You should start feeding your chickens layer feed at 18 weeks of age. This is when pullets (young hens) typically begin laying eggs. Layer feed has high amounts of calcium which is necessary for healthy egg production, but can be damaging to your birds’ livers if given before they start producing eggs. However, not all chicken breeds begin laying at the same time, so if your pullets start laying before 18 weeks, it’s appropriate to begin giving them layer feed at that time. 

How do I switch my flock to layer feed?

This is fairly simple, too. Create a half-and-half mix of starter-grower feed and layer feed for the first 4-5 days to allow your birds’ digestive systems time to get used to the new food. To make the transition process even easier, it’s best to use layer feed that matches the texture of the starter-grower feed they’ve been eating. So, transition pellet starter-grower feed to pellet layer feed, and crumble to crumble. After a few days, you can begin feeding your flock just layer feed. 

A few things to keep in mind:

• If you have a mixed flock (some birds under 18 weeks and some adults), it’s safest to feed them an unmedicated starter/grower feed with free-choice oyster shells in a separate dish. This allows the chicks to safely eat without limiting your hens’ access to the calcium they need. 
  
  
• If your flock is free-range, it’s best to feed them their layer feed before they go outside each day. This ensures they are getting all the vitamins and minerals they need before they begin foraging so they don’t fill up on less nutritionally balanced plants and bugs. Complete layer feed should make up at least 90% of your flocks’ diet. 
  
  
• Unless you have a legitimate reason not to do so, it’s best to allow hens free access to layer feed all day so each individual can get the amount of nutrients they need. 
  
  
• Chicken scratch is not the same as layer feed. Scratch, usually consisting of cracked corn and other grains, is mostly carbs and not a good source of vitamins, minerals, or protein. Access to scratch should be limited (think of it as candy for chickens).
