I'm sure it's advisable to never purchase chickens from a flea market, but I live in a farm community and decided to take the risk. I may have made a stupid decision and need some advice if anyone can help. I purchased 6 chicks from the farm store a few weeks ago and they have all been growing at a great pace and appear to be healthy. Today I purchased 2 from the flea market and being a new chicken owner, didn't really know what I should be looking for. Some of the chicks were missing feathers on their backs, but I asked the guy about it and he said he it was just from their fuzz falling out and their feathers coming in. I'm worried that it is from mites or lice, though. Or could it be something even worse? Or am I overreacting? Should I treat all of my chicks for mites just to be sure, or should I give them a few days to see if their feathers grow back? I'm totally regretting buying these now and I'm so worried that they are going to make the rest of my flock sick! If anyone has suggestions or advice, please help! Thanks so much!
