How long till a chicken is fully grown?

post #1 of 11
Thread Starter 

I have 13 wk BO hens and I was wondering when they will reach full size and weight.  They seem so big now but I know they do not yet approach the weight that the books say my breed will reach (at least they do not feel like it when I pick them up.)

First of all: welcome-byc

BO's will start to lay eggs at about 24 weeks, give or take. So, you are over halfway there!! Seems to take forever, but it will be well worth the wait smile

Thank you for the welcome!  So when hens start to lay is when they are full size and weight? (Sorry if this is a lame question.)

It's not a lame question at all!!!  How will know if you don't ask.  Around 6-7 months they are their adult weight.  They can start laying sooner than that though.  We have a BO that has grown substantially since she started laying.

Depends on the breed.  A LF brahma is not considered full grown until 2 years old!  If I'm not mistaken BOs are late to mature too.

Thank you all very much for your input.  I would not have thought it possible for some chickens not to be considered fully grown till they were 2 years old.  That's very interesting.  Does anyone know when a BO is considered full grown?  Also just out of curiosity what breed matures the fastest?

BO stands for Buff Orpington.

Matures the fastest or puts on weight and size the fastest?

A Cornish X puts on weight the fastest, they hit harvest weight by 8 weeks, however you hardly want a full grown Cornish X just hanging around.

As far as the fastest maturing more standard breed in not sure.
