Hello, I recently bought a 2 acre farm and naturally picked up 6 chicks last week. I grew up with horses and have a degree in Animal Science, but my college didn't have a poultry farm, so my experience with birds is limited. I am a high school horticulture teacher and am picking breeds based largely on personality so I can bring some hens in to the school for the kids to interact with occasionally (it is a title 1 school near the downtown of a large city, so most of the kids haven't had much animal interaction). I picked up 3 Buff Orpingtons and 3 Golden Laced Wyandottes on Friday (the 21st). The Wyandottes were born on April 12th and the Buffs were born on the 19th. I had them in a large Rubbermaid bin originally but just built a 3ft x 5ft plywood box for them as I will be adding 9 more chicks this Friday (which are probably hatching now). I have a couple of questions. First, is it ok for me to put the new tiny babies in with the other chicks, which will be 1 and 2 weeks old? Second, how long does it take for them to become friendly? I spend at least 30min - 1hr with them each day, they will eat out of my hand, but only one tolerates being picked up and petted without hollering so far (one of the wyandottes). Now that the brooder is larger I actually get in there and sit with them, but because it is larger it is harder to catch them and enforce loving on them, lol. Is this something that will get better as they associate me with treats or should I just chase them down and handle them despite the peeping/flapping? Oh, and one more thing, I have seen a lot of people on this forum mention giving yogurt to chicks, and I tried to offer some to them the other day, but they were completely uninterested. They just kept walking through it then obsessively wiping their feet to get it off. I tried sprinkling some of their chick starter in it and dipping a couple of beaks in it, and left it in there for about 30 min, but it was untouched. I have had more success since then with some pak choy (they have an overturned piece of sod for grit). Do I just need to keep trying the yogurt?
