I had two chickens, one was bullying the other. I followed the advice and added two new chickens. I brought in older larger chickens. Sadly the newest largest chicken is getting picked on by the other three. They don't allow her to eat the scratch I throw in the run... they seem to always chase her away and nip at her. They are all fairly young chickens. My first two are 19 weeks old and my two news ones I was told are 22 weeks. (I've had the new ones for two weeks now) Any advice would be much appreciated!! P.S. I was told my two new ones were laying... I haven't got an egg yet from the one that is being picked on! She's a Rhode Island Red. THANK YOU!!
