Irona

This bird gets its name for strong livability and good weight gain. The SASSO Irona is the heaviest of the portfolio of colored layers and presents dark grey feathers. The female average bodyweight is 3.640 at 75 weeks and male average bodyweight is 2.564 at 12 weeks. This bird delivers excellent meat quality as well as produces feather-sexable chicks. In addition to its weight advantages, the Irona also lays 286 eggs at 75 weeks, making it a great option for dual-purpose production. This colored layer is highly adaptable and easy to manage in all production systems.
