Hi all. I have 2 pullets 4 to 5 weeks old. They are very active and I have them out with me most of the day in secured areas of the property. They eat a minimal amount of feed at night while in the brooder. I would like to know is there any reason at all why I could or should not lock them in my greenhouse for the day? I grow with my own composted soil and straw bales. No pesticides or chemicals in it or ever used. There is a very shallow frog/toad pond with rain water in it. There it natural grass and weeds growing in about 40% the rest is dirt (which they love bathing in). Thanks for any help, I just would hate to not be thinking about something that could be a potential harm to these little girls.
