Hi folks. As quick as i thought our first night would be peaceful with our chicks...iv heard one sneezing and now has a snotty sounding sinus. Others are fine. Also do i need to create some additional warmth in their cage? They are inside a bedroom with two cloths over. They are nestled together on a log i gave them. Thank you in advance. Ps. Theres no blockages in nostrils. Eyes are fine. No bubbles or anything from nose.
