This is my first post to the forum. I live in N. Florida and have a small flock (7) of pet hens, barredrocks, buff orphingtons, and silver laced Wyandotts. I have always been very careful about keeping the birds protected against predators but, unfortunately, my Ft Knox chicken yard construction did not adequately take into account a pit bull wedging himself in behind a loose board. When I came home just after sunset, I chased the dog out the yard and found he had killed three hens and badly mauled three others. I took the injured hens to the closest emergency aviary vet 75 miles away and after lots of suturing have them back home in sick bay where they're getting topical and oral antibiotics. I think two will make it and its touch and go for a third. The three hens lost blood and had considerable lacerations and loss of some skin. Does anyone have a suggestion as to how I could improve their nutrition to help aid their healing? The are currently eating just their normal Layena Laying pellets. It seems like they should have something else, perhaps with more protein. They are in a 'recovery tractor' safe from predators and are being kept quiet and fed and watered well. Any suggestions on this or their care? Many thanks.
