Adaptations of a living thing are the structures it uses to survive  in its environment. For the waratah anemone, this includes red  tentacles that it uses to attach to rock â¦ s and to feed.
Best Answer: Lighter breeds (Leghorns and Sex-link pullets) will start laying anywhere from 4-6 months. They are bred for a higher rate of production and to reach sexual maturity faster. Medium sized breeds (Rhode Island Reds) will start laying around 6-8 months.
Factor #1 - Breed. Chicken breeds that are generally considered to be layers tend to lay sooner than those considered meat or dual purpose breeds. The hybrid laying breeds start laying as early as 16 weeks. Heritage laying breeds tend to lay about 4 weeks later (20 weeks) and all other breeds will begin laying between 20-32 weeks of age. I have no hard evidence to prove this, but I suspect that the breeds that lay the most eggs each year are also ones that are likely to lay the soonest.
