Crowing is not something that can be determined definitely. Several factors affect how soon they will crow, from depending on whether they are a dominate bird in the pen or not, or even if they are housed close to other dominate males can affect them. Having said that, I have had Marans chicks start trying to crow as soon as a couple of weeks old. Granted, they sounded like they were dying, but that's definitely what they were doing.Thank you! Do you know what age they start to fill out and crow? I've been seeing some of what I think are his feathers around so hopefully he's not fighting with the girls. Waiting for him to crow is almost as exciting as waiting for an egg.![]()
