Hi everyone, I have 3 year old hens, no roo. Almost all of them, I have 5 have been staying in their house all day, not accessing the run, and staying on their roosts, all day! But will Come down for treats. It’s in single digits here, lots of snow, no predators have scared them as I can see If any prints around coop. I will say the other day I did see my 2 sweet hens did gang up on my big buff Cochin whom normally is top dog or one of them. she did not back down and for the first time in 3 years I saw them use their wings and feet in a fight! She did not back down! I feel I have had 0 scuffles in my flock. No blood shed or bullying that I have ever seen. Are they bored? Is that why they are fighting? It’s been single digits and even negative degrees here this last week. My question is, why are almost all of them staying up on their roosts every time I go out to check waters and eggs? I am cleaning out and shoveling out the coop tomorrow, new sand and new straw, I am hoping that will distract them and get them on to something new and different. Any advice would be appreciated!
