my hens have went from laying 10-15 eggs a day to 3 eggs in almost 48 hours we were mid 90's all week but today i has cooled off thankfully. i did change feed on them on monday but went to a higher protein went from 21 to a 28 because i added in some 7 weeks olds and thought i should give them a lil more protien to get them started off right.from my previous experience my cotunix have always laid well in the heat and i have fed 28% before with no problems so i am stumped on this one.....any suggestions????
