egg laying behavior

[realsis]

hi all I have a silkie pullet that's just came into lay. when I bought her she laid her first egg at the breeders then when I took her home she laid another. she was off lay for about a month to be expected because of a new place. three days ago she came into lay again but it seemed she was having a difficult time as she was panting and had her head down. after she laid the egg all was fine. this morning again she was panting and had her head down. then the egg came and she's fine. do you think this is just normal behavior for her when she lays or is she having trouble? or is it she's just young and getting used to laying? what's your opinion?

I think it's because she just started laying.

Are the eggs bigger than normal silkie eggs?
