I have a show line and my birds started laying around 20 weeks, and havent stopped yet. They started laying in the middle on Jan and for 3 months I got 4-6 eggs a day from 6 birds. The issue with show lines usually arent how long it takes for birds to start laying, its birds that dont really lay well.My two MFCs didn't start laying until they were 10 months and a year old. Show lines take even longer I heard.
