Hi! I am new to BYC and to raising baby chicks. We dove in head first this spring, intending to get 8-10 and how have 27 Everyone has been happy and very healthy so far. I've noticed over the past week a couple of my 5 week old Lavender Orpingtons are making a weird squeak noise as they peck around. The best way I can describe it is like a sneaker on a gym floor. Also, occasionally a song bird kind of sound too (not as concerned about that). Is this squeak normal? I've read about early crowing and it's not a long or loud squeak and they don't stretch their necks out...its like it has taken the place of their cheaping. They seam happy and are eating, drinking and active. Could it be that they are little roos? I have all of the 5 week old birds (14 of them) in a 10x5 dog run with a branch for a roost in the garage, and still have the heat lamp in there between 70-75 degrees. I've added a little ACV to their water off and on. Just want to make sure there's nothing else I should be doing or concerned about! Thanks!
