A couple of my 6-week-old chicks have started pecking my fingers whenever they are in the brooder. It started with my Delaware, and now my BR is joining in. Is there anything I can do to stop this? My 7 chicks are currently housed in an 8 sq.ft. brooder in my kitchen which is the best I can do for them space-wise for another week or two when their coop will be ready. I don't know if that would be an issue or not. They have plenty of food and water, and I try to give them a bit of entertainment at least a couple times a day (treats, strips of paper, plastic toys, etc.) Any advice on how to curb this behavior?
