I have 4 chickens that are around 4 months old. Truth be told, my daughter and I caught them at someone's house by net when they were biddies. No one was exactly sure when they'd been born but they were already getting feathers and were still small enough to fit in one hand. Anyhow, they are MUCH bigger these days. I think that 2 are roo's and 2 are hens?? Today I watched 2 of them acting like they were going to fight. They kept watching each other's every move and they'd get face to face with their neck feathers blown out. It seemed like they were almost flirting-a love/hate relationship if you will? Every time one walked away the other would start it all up again. They have an 8x8 coop. We built 4 separate nests. I don't let them out an account of our dogs who are inside primarily but do run in our fenced in backyard. I wonder what this behavior means between the chickens? Is is bad to have 2 roosters, if in fact that's what I have? I think that the two I watched behaving in this manner are a rooster and a hen, which is why I felt it was a flirting thing? Also, they are messy as all get out!! Poopingest things I've ever seen in my life! What's the best stuff to use for their nests and on the ground? I've got pine straw at the moment. Seems like cypress chips/shavings would be too much cost wise, especially since I will be doing a huge amount of cleaning up in there! I was appauled that they poop in their nests, their water, their food! GROSS! I can't believe I eat them. I love having them though and I can't wait until they begin laying! Had no idea it took so long!
