While we were gone over Thanksgiving week, we had my in-laws checking on the chickens once a day and collecting eggs. They reported nothing amiss, but when we arrived back Sunday night, we discovered a blood bath in one corner of the coop and one hen had a badly pecked comb. It must have happened that day, as it's the only day nobody checked on them.
So Monday morning we pull out the injured hen and put her in a dog crate in the garage. I had some Blue-Kote on hand that I'd bought but never used, so we applied that to her comb on the advise of some sources on the Internet.
Later that day we tried to re-introduce her, and immediately every chicken was on the attack.
Since then I've moved the crate into the coop, where the newly blue-headed lady spends her days.
I've been doing supervised interactions - one that went well, and one that went badly (today).
If I just continue these supervised visits, will the others eventually leave her alone? Would free-range be a better way of interacting versus inside the coop? Should I dye ALL of their combs blue???? My understanding is this stuff will take quite awhile to fade.
They are acting vicious, and have already drawn blood again during the disastrous session today. We are right at the beginning of many of the hens beginning to lay, which I understand can increase aggression.
I'm definitely regretting ever using the dye, as it only served to make her stand out more.
