I have four almost 22 week old Buff Orpingtons. Two of them layed their first eggs today(picture attached) but they have very odd combs. They are HUGE and the end is turning purple. I have one good picture of it but the other chicken wouldn’t stand as still. They are being fed Purina flock raiser with oyster shell and grit on the sides. They are on grass in the evenings and are fed occasional treats(once a week). No problems with behavior at all, they are all super alert and eating and drinking well. What is wrong? Is this normal?
I don't think it is normal. I think there is something wrong.
I've had 3 cocks in the past whose combs went purple; they all died.
I took one to a vet, with a shit sample and the vet thought it could be heart, or liver problems, but no obvious disease. It took a couple of months for this one to die. He was active and seemingly healthy right up to his last few days.
Another was fine in the morning, comb bright, active and eating. That evening his comb went purple and limp at the top. The next morning I found him dead on the coop floor.
I've read, that too much calcium in their diet may be the cause; I've also read that this is unlikely.
I've read that it's a genetic weakness affecting internal organs but nobody seemed to know what to do.
Since then I have learnt that nirate poisoning is one cause and can be treated with methlyene.
If it's the heart, there are treatments ACE inhibitors. You will need to look on the web.
.The problem is getting a correct diagnosis.
I hope you can find better answers. Good luck
