Two weeks ago I bought 2 4 1/2 month old BR hens. During the trip back one got poked in the eye. I started washing the eye out and putting neosporin on it, but it kept getting worse. Then I notice they had lice and mice and treated them for that and it worked. Then both hens started to get bubbles in their eye and wheezing , so I cleaned the eyes out everyday and still they got worse. I then started them on duramycin and still got worse. Today I decided it was enough and had my husband put them down. I'm sad. This is my first attempt at raising chickens. I have a BR roo and some kind of game hen and hope they don't get what the others had. They are not showing any signs, and they were not housed together and I know that is no guarantee they wont get it. I don't know their history since they adopted my yard during the winter. I only wanted a couple more hens for pets and of course their eggs. Will this cause problems in the future if I decide to get more hens? I only have the 2 chickens and would like to add 2 more.
