I purchased three laying barred rock hens yesterday, got them all settled and happy in their coop and run. They roosted just fine last night but now today two of the hens havent left the coop at all. Are they just getting acclimated and I should leave them be, or do I need to toss them out into the run to eat and drink? I do have a second waterer in the coop but I haven't seen them off the roost at all today and it's pretty hot here today.
