I have 12 guinea keets, approx 10 weeks old in an outdooe pen. I just acquired 2 peachicks, approx 3 weeks old, and so smaller. I plan to keep them under a warmer for antoher couple of weeks. (temps here are hot and humid during the day, but cooler at night). My question is whether I can then put all the chicks together in the outdoor pen. I am concerned the keets will attack the peachicks, but they seem to be substantial birds. Thanks for any help!
