I'd avoid BluKote, and would much rather use Silvadene (brand name) which is an excellent antibiotic wound dressing, Rx only in the USA. Ask your veterinarian or MD about it. It's a sulfa drug, so handle with great care if you are allergic to sulfas.
Very recently we had an injured pullet, I...
I agree with @McChooky, keep the year old and the four month old for now, and see how they get along, and how the youngster develops. Either or both, or neither one, might work for your flock.
I also wouldn't keep those chicks by your nasty rooster.
Take the time to evaluate these birds...
We had good success with birds from MMcM, and the one time we got a Fayoumi cockerel as the extra chick, he was lovely. He started crowing at 28 days of age, beyond cute!

Yes, alfalfa is different, higher protein, and richer than grass hay. You need to look up what's best for your guinea pigs, and then buying actual bales of hay rather than those cute and madly expensive bundles at the pet store makes more sense.
Either types of hay can vary in quality a lot...
Much easier to feed the medicated feed, rather than mixing meds in drinking water, and hoping everyone gets the right amount, and actually drinks adequately.

Permethrin powder, especially in cold weather, or permethrin spray concentrate, when it's not freezing out there, are both inexpensive and work very well. Spinosad is a much more expensive spray that also works well, and bot products are approved to use with no egg withdrawal.
Products labeled...
The amprolium medicated feed is needed to continue for two or three weeks after the chicks are introduced to their environment. Stopping it when they are introduced to the dirt they will be exposed to is not helpful!
Better to use the medicated feed long enough, rather than using the higher...
Pepper gel? Have to look that up.
I talked to a police officer about the gun that shoots pepper pellets that explode on contact, he said very bad idea! It's a one shot at a time, reloading after every shot. Terrible idea!

Last I heard, the GPS type IF isn't as safe or reliable as the real thing, and the GPS is not accurate to the exact fence line desired. Things might be improved, but check very carefully before buying this type of system.
Nothing is perfect! Our real fence and IF work very well, except for...
Take pepper spray, at least and practice with it first, so you don't hit yourself if it's needed.
And did you report this incident? talk to the dog's owner, or send Animal Control or the police?

So sorry...
Could a critter have gotten under your fence? At night a raccoon could have climbed over that fence, and either a hawk by day, or an owl at night, could be involved. We had rats invade our coop one year, and had birds killed at night by them.
Any tracks outside? Tufts of fur or...
