I have a broody Welsummer...she could not be deterred from the broodiness despite all my efforts so in the end I bought her some fertile eggs to sit on. She's been going for 9 days now. I'm concerned that she isn't eating or drinking and I've had two different responses to this when I have asked people who breed... some have said that she will just go for the full 21 days without moving, eating or drinking...and then others have said she needs to be encouraged to move, stretch, poop etc etc... is there a right answer? Her comb is looking dry and a little drooped so I don't want her to lose too much condition just because of these eggs. Any advice would be much appreciated.
