1.)My chickens male and female are losing feathers just before their tail. They turn white and fluffy then I'm not sure if they are falling out or one of them plucks them out. They are 6mos. old. 2.)egg production was 11 a day, it dropped to 2, and just today we are back to up at 10. We went on vacation and it has been hot. Caregiver may have something to do with it(?). 3.)my Buff Orpington has/had stopped laying, however she is sitting on all the eggs. I think she is back into laying, today I noticed her egg color in my collection today. 4.)I have a Americauna rooster and one female Americauna along with many other breeds. How am I getting 4 blue/green eggs a day. Can the rooster make others lay that color of shell or does the female determine the shell color?
