Our white giant was healthy and thriving. Then we noticed a downturn. He stayed in the coop and didnt want to come out. When he did he was on wobbly legs. He started getting worse to where we thought maybe has wasn't eating. We removed him from the coop and noticed he was full of lice all over him. We took him home and bathed him and fed and watered him good. The next day he was more responsive and trying to move but couldn't. His comb was also looking better it was before turning black but it is now turning red again but he still won't get up and walk. He tries but can't support his weight! Anybody heard of this or have any info?
