I currently have four hens in a 54 gallon tote that is indoors that were born on 11/25. One of the birds is able to hop onto the top of the one quart water screw on jar made by miller manufacturing. My fear is that one day I'm going to walk in to check on the hens and find that one of them has escaped. Is this hen trying to roost on top of the feeder in that I need to change it out or do i need to add a open top grate to the tote to secure it? Thanks for the help. As you can see by my post, I am very new to this.
