I am on my second batch of chicks. I learned the hard way on my first batch. One died after a couple of days and then after they got big my dogs finished them all off but one. She is doing well and laying. I have many questions. When can I introduce her to the chicks? They are in separate pens but they can see each other. Also she has been acting strange and not eating much, but I don't know why. She doesn't seem sick. Any advise would be appreciated. Thank you..
