Hi, I am trying to breed a pair of beautiful red factors. I was not lucky with the first two broods, because I suspect the male killed them. However, 3rd time round, I removed the male close to hatching date, and the female has reared 4 chicks. They are in their 4th week and feathers are starting to show. My question is…..why do the feathers seem to be growing white?? The pair are both very red. Thanks.
