It doesn't take very long.
The amount of time it takes for a pet to grow varies, but you should see your pet start to grow at about 12 days and become fully grown at about 25 days.
From what I've read, usually about 8-10 weeks old. There are breeds of chicken which gain several pounds in that span of time and which would have health problems later in life if permitted to live.

how long does it take pseudomonas to grow in a bottle of water?
How long raw chicken can be left in the trunk of the car depends on how cold the chicken is to start with and the temperature in the trunk of the car. From the store to home should take no more than 20 minutes. If it takes longer than that, bring along a cooler with ice and place the chicken in that. The warmer the chicken gets - or the longer the chicken stays warm - the more bacteria will grow and the chicken will spoil more quickly.
