Hello -
Good news:
The chick survived having her leaky yolk sack tied off with dental floss and removed. She appears to be flourishing with no sign of the ordeal she went through, so I put her back with mom and her 4 siblings, and she is doing fine. I can tell which chick she is, because she runs to me when I stick my hand in the brooder - the other chicks dive under mom!
Bad News:
A disease is going through my flock. I have never had this happen before.
I had a hawk attack a rooster early June when my birds were out free ranging. He vanished for 3 days and came back missing most of his feathers and had 2 rips down his back. I put him in my bantam coop to heal, and when he was strong again, I put him back with his flock (about I have 14 hens 7 pullets and 3 roosters in a large divided coop, hens and roosters on one side, pullets and younger hens on the other with just hardware cloth dividing and broody hens now with chicks hatching in a store room in the same building, but a solid wall between them and the flock; the bantams are in a separate coop). The hens ad roosters free range. The pullets and young hens just get their coop and run.
A few days ago there was a sudden drop in egg production, and it has not picked back up. I assumed the EE's had made another nest in the woods as they often do. Yesterday I was out in the yard feeding them treats and asked them where they hid their nest when one bird cocked her head as if she were listening and I saw something in her eye. I think she tipped it to see if I had more treats. There are bubbles in the corner of her eye. I inspected the rest of the flock, and found the rooster and one other EE also have the bubbly eye thing going. No one is coughing, rattling, nor sneezing, no head shaking, and they are going about their business as usual. Poops look normal, no dirty butts, but I am also not going through the same amount of feed I typically do, but my orchard has ripe plums, and I have 30 blueberry bushes that they have been raiding. I smelled the sick birds faces and noticed no bad odors. In past years, I had always used Oxine in their water, but have not done so this year since early spring. The pullets and young hens appear to be healthy. It is my old birds that are getting sick.
I am going hunting for Tylan tomorrow. I bought Duramycin and Sulmet, and made up some of the Duramycin for the drinking water, but before I got it out there, I noticed the bottle read "not for poultry producing eggs for human consumption". So they did not get it.
Do you inject the entire flock or just the sick ones? Do you use a fresh needle and syringe per bird? Can I just inject the sick birds and treat the water for all chickens with tylan? Do I do anything for the baby chicks?
