Abstract: The study was evaluated comparative growth and age at first lay for Fayoumi and White Leghorn and their F1 crosses from day old to age at first egg. For this, a total of 176 chickens from each genotype as foundation stocks were randomly selected and naturally crossbred to obtain pure Fayoumi, White leghorn and their crosses. A total of 1000 eggs collected and incubated on the 7th day of post oviposition. Among hatched, a total of 150 chicks selected from each genotype for subsequen...
