Hi everyone. I am new here and have a question I just can't find an answer to so I thought I would ask the experienced folks here. I have been keeping chickens for quite some time now, but have never experienced mothering behavior like I have seen from (strangely enough) my Black copper marans x Ameraucana cross. She has 5 chicks (3 boys, 2 girls, boys are for meat, girls are for laying) are now 11 weeks old and she still will not stop caring for them. This was her first time going broody, so she is a first time mom and she is very young (went broody at 8 months old). She has done an amazing job with her chicks, but doesn't show any signs of separating from them. All of this would be great but I have to keep her and her chicks separated from the rest of the flock because she is so hyper aggressive with the other chickens (including my rooster). They are currently confined to the upper run of my chicken coop (I have one 4x6' coop with an attached lower and upper run. The lower run is 8x10' and is where the established flock resides when not free ranging. The upper run is 6x8' and is where mama and the chicks are confined. The established flock sleeps in the coop at night and mama and the chicks have shelter and a roost that shares a wall with the coop. Everyone can see, hear, smell and interact with each other at all times; the only thing separating them is a wall of chicken wire). I have attempted numerous times to allow mama and the chicks to free range with the rest of the flock but her need to protect her chicks results in serious fights. In the past with other mother hens there has always been enough room for everyone to share free range space and mama and the chicks just kinda do their own thing and everyone leaves them alone, but not with this mom. It seems like if any chicken gets within 20 feet, she attacks. Mama even tries to attack through the chicken wire! (note: strangely enough, she is incredibly docile with me and lets me handle her and her babies regularly) So, my question is, has anyone ever had a mother hen that was, well, too motherly? In my experience, usually the mom has fully separated from the chicks by 8-9 weeks and wants to be back with the flock. Am I being too concerned and impatient? Is there a way to get her to leave those chicks alone so I can re-integrate her into the flock without feathers flying? If not, anyone have any tips on a more successful integration? I usually have new pullets integrated into a flock at about 14-16 weeks, and that is my target time for these chicks, as long as mom lets up! Thanks everyone!
