So, the plastic bins that I've been using for my 5 chicks are too short for them and not enough room since they're 3 weeks old now and can fly out of the bins...so I went to Loews and bought some hardware cloth and I was about to make a 'kennel' for them (thinking I was being sly because I can reuse it for around their coop/run when we're ready to move the chicks into their permanent home). And I go to open the package and the package says ...to the state of California...known to cause cancer and reproductive harm...well, should I be using this? I was healthy laying hens...and the reason I started this hen project was to help my family and I with our allergies and issues with chemicals and stuff. It looks like its used widespread. If I make a 'kennel' for the chickens will this hurt them? I'm still laying down shavings for bedding. I don't want to over analyze everything I do, but my point in doing this was to do things that were good for us and the environment...teaching my kids sustainability and self-sufficiency that's good for the earth and us. What do you think?
