Okay, new chick mama here. We have 50 freedom rangers chicks on 3/8. One died we believe from suffocation on 3/10. Chicks have been growing great!! Gave them electrolytes in their water until last Thursday. Changed out their bedding on Friday. Yesterday, put in a new feeder at 2 and at 3:15 there was another one dead with beak stuck in corner. Pretty sure it suffocated too. Put carboard in corners to round them off. All doing GREAT!! Got up to use the bathroom at 1, checked on them sleeping soundly. Checked on them again at 7. Still GREAT!! Went in at 8:45 to refill water and food. No problem, while filling up water, I hear a broohaha in the brooder box and all the chicks have fluttered to one side and one chick no in a corner but near the electric hen, is twitching. It died. I left it there because, I know sometimes their little hearts can restart, it didnt. Any thoughts? We have 50 freedom rangers in a 4x6 box. We're using lrg shavings of pine for bedding, we have a electric hen, and heat lamp suspended about two ft above box. We have given them electrolytes for a week. Using PDZ for smell because they are in my garage. Their poops are well formed. Thoughts?
