I currently have (7) year-old hens and (9) 11-week-old chicks (1 of which is very likely a roo). We brooded the chicks in the coop from day one (minus a few too-cold days when we brought them inside). Their pen is directly beneath the roosting bars/poop board, so I'm assuming the big hens are already used to and familiar with the babies.
The chicks are starting to outgrow their pen and I'd like to give them more room as soon as possible. I have been waiting for the hens to finish laying for the day, then closing off the coop and letting the babies have free roam in there without the worry of the big girls messing with them, but I'd love to be able to let them out in the run/yard with the big girls too.
Our big girls are very docile and sweet, they never fight with each other, even when they're bored.
Is it too soon? The babies obviously aren't the same size as the big girls yet, so I'm not sure if they're still too small at 11 weeks to hold their own. Thoughts? Anyone with a similar situation that had success with integration at this age?
