Exactly how old are these chickens? They sound like cockerels just coming into their maturity... they are mostly hormonal nightmares. I processed 4 of my boys, and have several others on a list of joining them in freezer camp soon. I was shocked to see in cleaning them that their testicals are larger than their hearts. Literally. Testosterone poisoning at work.
They are geared for species survival in an unmanaged environment, not as domestic “pets”. You need to get the extra boys far away from your hens now, before they kill them in their enthusiasm to mate. Cull for dinner or dog food (humanely and fully process them don’t just give your dogs the carcass), sell, give away... but get rid of them. Tony sounds like he should be top of the list... I understand attachment, but you NEED To get past that if you’re going to keep chickens, or only buy pullets at point of lay or sexed chicks.
If you care at all about your animals you need to address your situation. (Nothing against vegetarians here... don’t get me wrong I respect the decision) But people with “morality (animal welfare) based” vegetarian ideals should not breed or buy straight run chickens. In nature the “boy problem” would sort itself out with predation, in an artificial environment we have to serve that role, it is unfair to the chickens to put them through this.
