I bought a new sea bright bantam hen today, and she has a runny nose. It was more of a rescue. Well I put her in the isolation coop...my dad comes in thinks she just got out, and I left the door open to this coop and she went in there.. well he caught her, and put her with my whole flock! She's been in there all day with 15 two week old chicks, and their mommas and everything else. Should I leave her in there since she's already mingled with everyone and ate with them and sneezed on them.
