Hi chicken people!
So I have three different groups of chickens, and I wanted some suggestions on who I should introduce to who first! I just want to make it easier on everyone involved. Sorry for all the questions, this is the first time I've had a rooster and this many hens!
Group 1: Two mature hens and a rooster
Group 2: Two mature hens
Group 3: Five pullets (14 weeks old)
Should I introduce the mature hens to each other first? Or should I introduce the pullets to one of the groups first?
Also, should I separate the rooster and introduce him by himself after the girls are getting along? He is very protective of his girls, always doing the "dominant wing dance" through the fence at the new hens. Hopefully that isn't a bad sign and he'll come around to them!
Thank you for any and all suggestions!
