So last night after I had put the pullets up in the coop and locked it, I went out to check on them and noticed that 3 were on the roost, kinda, but huddled up in the corner nearly on top of one another positioned out from being directly by the opened screened in window adjacent to the roost which is circled in the attached pic. The other three were up on the window ledge of said window. I have ample roost space there but I am wondering if perhaps they do not like having the window that is right next to the roost area open at night while they sleep? I have 2 other windows and screened in soffits as well for ventilation. I plant on putting another roost higher up where the ledge is that the three were perched on because the bigger they get the less room that will be on that spot. So my question is, should I shut the window that is next to the roost at night or leave it open? Thoughts? Opinions? Concerns? So you folks who are more chicken experts speak up! Lol!
