More info please:I only have two older hens; an old bantam silkie and an ancient bantam Americauna and the two roosters are quite protective of all of their hens.
Your flock size(numbers, ages, genders)?
When did you add younger birds?
Coop(size in feet by feet with pics)?
Oh, and.....
Where in this world are you located?
Climate is almost always a factor.
Please add your general geographical location to your profile.
It's easy to do, then it's always there!
