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?
