Hi everyone, We are new to raising chickens. We started with 4 eight day old chickens. One unfortunately died early on. The 3 remaining (1 sussex and 2 rhode island red) are going well and are now 16weeks old. We would like to get another chicken to even it out but now sure to how to go about introducing them. If we are going to upset everything I would not go ahead. I heard it's better to get a similar age for eg? Thanks Vicki
