Most layer feeds are 16%. Many of us feed in the 18 - 20% range with no problems. When you start going higher than that, long term, it could cause problems for chickens. Some of the game birds need the higher protein. I've been feeding 18% for years and it's fine. I don't use layer feed...
If it was like this always, then it could be a congenital defect. Something like coloboma (a defect present at birth) (it doesn't look exactly like that), if you search you will see pictures of what that looks like.
Scarring from injury can make it look deformed as well.
Does the pupil react...
No, I would not treat them that way. You need to know what you are treating for before just randomly trying to give them antibiotics. The wrong medication could make things worse.
80 square feet for 30 hens is pretty small.
The bird pictured with the beak/wattle injury, hard to say, could have gotten caught on wire or feeder, once bleeding others would peck at it and make it worse. Her upper beak was a bit overgrown as well.
If you have the body(s) of the most recent...
At this point it doesn't look like the Marek's eyes I have seen. Does she appear to have any vision in that eye? Does that eye react to light at all, or movement? Was the eye normal before, that you can remember? My guess is more that it may have been an injury of some kind, but I would keep...
Did you give them the oral dose? I would also give them some of the medicated water several times a day directly orally, until they start drinking. The medication can't work if it doesn't get in them. The longer they go without treatment, the more damage is done to the gut, and the more...
I'm so sorry. :hugs
Yes, that's possible. Mycoplasma is very common. The treatment is usually Tylan or Tylosin, I would try that to see if it helps. Link below to one source. If that is what it is, the medication will treat the symptoms but it is not a cure. MG (mycoplasma gallisepticum)...
Yes, I would do the 5 days in a row. If you want to be completely sure you've got them all you can do one single dose again 10 days after the last of the 5. In the future, if you want to get Valbazen (labeled for cattle, usually have to order it online), dosing is a little easier. With that...
No, not contagious to you. Coccidia strains are generally species specific. There are about 9 strains that affect chickens, those do not affect humans. Having said that, reasonable hygiene practices are always a good idea, washing hands etc. I've had chickens for 15 years and have yet to...
Dose of that is .23 ml per pound of body weight, orally. If you don't know what type of worm you dose that 5 days in a row. If you know it's roundworm only, you can do 2 doses 10 days apart. If what you saw looks like the image below, those are roundworm.
To give, shake the medication well...
Vitamins are ok, both of those have a 10-14 day withdrawl after treatment. Many ignore it. Both medications are used in humans. I used to toss the eggs, I don't any more. If you are concerned, then follow the withdrawl.
There is no egg withdrawl for Corid, it's perfectly safe to eat the eggs. It's also perfectly safe to eat any eggs you have already gathered. Whatever the water is in is fine, they just need to drink it. The only caveat I would say is that if the water in the open bowl is getting dirty, you...
I'm so sorry. It's always hard to lose them, but particularly when you've worked hard to save them. Sadly, sometimes it's out of our hands no matter how hard we try. I'm really sorry you lost her. :hugs
Yes, you can worm them. I would use either Safeguard liquid goat wormer, Safeguard horse paste, or Valbazen (labeled for cattle). Those are what I use most. The Safeguards are usually available at most feed stores, the Valbazen you may have to order. They are all given orally, directly, not...
Make sure you do the full treatment time, do not stop early because they look better. If they are slow to recover, do the full 7 days. Corid is very, very safe and won't hurt anything.
How old is the bird? Internal parasites, drinking lots of water if it's hot, something in the diet, reproductive problems, pretty long list of possibles, those are probably the most common. How is her weight? If she's thin, that could also be parasites. If you have vet that will do a fecal...
