Our brooder is in the chicken coop so our hens have seen the chicks for about 3-4 weeks. Today I let them hens roam and put the chicks into our covered run to play and explore. The hens went into the run and seemed to be doing good. Then a couple of the hens started chasing the chicks and pulling a bunch of feathers out of the chicks. I no this is normal but what is too much and to start getting worried? I made a "Safe box" that only the chicks can fit in so they can get away if need and they were using it. I eventually got the hens out and blocked the small coop door so they cant get in to give the chicks a break. Is it best to just let them do their chicken thing so they know whos boss? Lol! This is our second year with chickens and first year having to introduce chicks to hens. Any help would be great!!!
