This evening I went to check on my 8wk. old chicks. When I turned on the light, I saw one gape serveral times, then stop. I've seen some of the others do the same occasionally. They (unfourtnately) are still in the house in the brooder. I have 3 in one and 3 in another. The heat wave we've had here in VA really slowed down any work on our new coop. They are eating chick food and no "treats". What should I do, if anything? I was reading a little about Ivomec. Is that an option for such a young chick?
