I use flock raiser, my store has several brands, I get what is in stock. It stinks that Purina is so expensive, but it's gone up a lot the last few years. I also use an 18-20 % grower feed sometimes, never had a problem with that either.
Safeguard is .23 ml per pound of body weight, dose once a day for 5 days in a row. For calcium, calcium citrate +D (citracal or generic equivalent) is better absorbed than some other forms, but you can use calcium carbonate as well, I aim for 400 -600 mg once a day for a week or two to see if...
My birds with OMD also live a long time. Seems like when the disease goes there it's just somehow less virulent. I currently have one old bird who has had symptoms for a very, very long time, is completely blind and lives in her own enclosure. She's like the energizer bunny, just keeps going...
I usually keep them wrapped until they are completely healed. It's a judgement call on your part. I want to protect that new tissue until it's all healed so that it isn't re-injured and we have to start over. Wrapping gets easier with practice. Just check often, make sure it's not too tight...
Is there still a wound that needs to be kept clean?
If you are using vet wrap or co wrap, just wrap it tight enough to keep everything in place. It's easy to make it too tight, you have to be careful of possible swelling after bandaging that can sometimes cause circulation to be lost. I...
The Elector PSP would work for both birds and the coop, and it's supposed to work with one treatment, rather than the at least 3 needed with permethrin. Most use permethrin because it's less expensive and easier to get, but either is effective.
The dropping looks pretty normal, feet look normal, oil gland looks normal. I'm going to attach a link on lice/mites that has pictures, and treatment options. If in doubt, I would go ahead and treat them and the coop. You will need to remove all bedding and nesting material, dispose of it...
Try not to panic. I'm really sorry you aren't seeing any improvement. If you lose this one, I would highly recommend that you send it to your state lab for necropsy, (link to list of labs below, call your nearest and ask for particulars) to find out if it's Marek's or something else. Other...
If the bumblefoot has resolved and there is no swelling, redness, etc. then she may just have sprained or strained it. It happens, jumping down and landing wonky, etc. Could have been compensating for the bandage if it was bothering her, or could be completely unrelated. If she's getting...
...you are seeing blood in droppings instead. If droppings are normal, and as you said they are all acting fine, then likely that is what happened.
*EDIT* as an aside, I noticed loose screws on the window ledge. While they are apparently (?) large ones, I would remove those so that they don't...
Good pictures of the wound would be helpful.
The feet look like they have some small injuries, nothing that looks like full blown bumblefoot now. I would just treat the small area's with a topical ointment daily.
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...
