I have two chicks that I brought up to the house to treat pasty butt and one of them was small and not thriving. Figured out the small one was the only chick out of 28 that hadn't figured out the Brite tap. They have been in the house under a heat lamp for 4 days now and the pasty butt is cleared up. The small chick is still small, but healthy and active. The chicks in the house are not happy, they seem frightened and I would like to put them back with the remaining 21 chicks.
I plan to put the small fountain watered in the brooder for the small chick until I am sure it is drinking from the Brite tap.
I don't want to lose any more chicks to "newbie learning curve" so my question is
What do I need to be aware of or do when putting these two chicks back into the brooder with the rest? They are all 10 days old.
