Hens with eye infection - treating them for a upper respiortary infection

[Buckmaster]

Hey just joined this site, can someone answer a question i have.
I got 12 barrock hens, i had three come down with a eye infection, l have been treating them for a upper respiortary infection.
Gave each hen 1/2 cc of LA 300 2 of them r looking a lot Better.i notice the one hen that got sick last still has a swolen eye.
How long should i wait to put the better birds back in the main flock.
I have been treating the healthy of the three for 9 days.
The sicker one for only three days?

If what you're treating them with is working, then don't stop treating the sickie.
I would wait... about a week without treatment before you put them back.
